Shouldn't the Okavango Delta be on this list?

And while we're thinking about places in Africa, how about the Nubian Desert (Egypt/ Sudan) and the Rift Valley, which is another place which can be seen from space?

No one's mentioned the Uffizi Gallery yet, or the Ponte Vecchio, or Kashmir and Dal Lake, or Chartres and its wonderful mediaeval stained glass.

John Reid, Wellington, New Zealand

I dislike lists because they are inherentently biased and ultimately assume that everyone has the same tastes. They do, however, tend to inspire soul searching, leading people to places - not just ones on the list - they'd never thought about before. And maybe see beauty in places they'd never considered beautiful.

As for me, I'm not too cool to absolutely love Disney or to have a fantastic time at the most touristy places a city/state/country has to offer. I also make an effort to "get off the beaten path" wherever I go. The giant industrial shipyards in my adopted city of Mobile Alabama can be just as amazing to see as Ankgor Wat or Petra if you look at them for what they are.

I'd love to see it all and make my own list.

Aileen, Mobile Alabama, USA

I say Dunn's River Falls and the Blue Mountain Peaks of Jamaica, followed by the Pitons of St. Lucia in the caribbean , The Aya Sophia and and Mount Nemrut in Turkey

eri, Kingston, Jamaica

Don't forget the Great Northwest of the USA. The awe inspiring Crater Lake, the Oregon Pacific coast, Hells Canyon, Mt. Hood, Mt. Rainier, the San Juan Islands near Seattle. Trully a glorious, rather unspoiled part of America.

Tom, Boynton Beach, USA/Fl.

I've traveled to about 80 countries all over the world and I've seen most iconic landmarks, with a few exceptions, such as the statue of Jesus at Rio. The Pyramids, the Taj, Great Wall, Angkor Wakt etc. I've been there and done that. -- I had a job that enabled me to travel. I've also been all over the US; 44 states so far, including Hawaii but not Alaska, yet.

My take:

New Zealand is the most beautiful place on earth and it has the friendliest people.

Sudan is the bleakest I've been to, but has the most hospitable people.

Sri Lanka and Malaysia have the best food.

Idaho is the most specatularly beautiful state in the US. NJ is the ugliest.

Every large city has a parallel universe for tourists. Human nature is the same everywhere, but culture is not.

To find true happiness forget tourist experiences, go do something for another person. It's more beautiful than any sunset on any beach. Tread lightly on the earth. If you find a special place, keep it secret.

Paul, London at the moment,

Las Vegas? Give me a break. "Mandalay Bay", what a joke. Mandalay's some 200km from the ocean.

Andrew Milner, Karuizawa, Japan

Sorry- Bryce Canyon is in Utah not Arizona. But it's still amazing as are the canyons of Arizona. Even The Grand Canyon if you escape the touristy bits.

Jenny Tayoir, Manchester,

The top wonder of the world is London. Think about it Frorm ancient Rome to the 2007 avant garde, it has something to offer. Don't leave home, to see the wonders of the world, spend your money enjoying what you have at hand. I wish I stll lived there

James Milholland, Roswell, Georgia, USA

"Arsenal's Emirates Stadium in north London. Specially when Thiery Henry is playing..

C. KOSE, Kocaeli, Turkey"

I think this says it all:
This guide may be a start but who is to tell who what is a wonder of the world?
If it stirs you, makes you think, arouses something inside of you...why can't it be your wonder of the world?
People need to learn to appreciate other peoples views more =)

Dave, Birmingham, UK

stone henge stone henge stone henge

jules, esquel, argentina

...also. i have to agree with the Salar de Uyuni - but i think it is far more impressive a wonder when it is entirely covered with a few inches of water. perfect reflection of the sky and clouds, and the pyramids of drying salt doubling up to look like UFO's as you drive/feel like you are floating across this immense mirror.
i can also recommend buying dynamite in Potosi and blowing up piles of salt at the salar for extra fun. and on the other side of the cactus island there is a cave well worth sleeping in once your alotted place on the other side has been stolen by hoards of isreali back packers. the sun rises over the salar which is orgasmic.

jules, esquel, argentina

hang about - what about Stone Henge in england?? a true "wonder" in that they still don't know how it was built or what it was for(see Spinal Tap)- an iconic image known all over the world, surely must be in the top 25 wonders...

jules, esquel, argentina

I know it's now part of China (tragic - the mess they have made of the place) but the Potala Palace is Lhasa is still an extraordinary man-made wonder. A lot of modern architects could learn a thing or two from it. Not so wonderful inside but when you first see it.......

martyn craft, haverfordwest, wales

Surely the original idea behind “Great Wonders” was that they should be man-made and visually spectacular? In that sense Las Vegas is a very sound choice despite all the pseudo-snobbery derision heaped on it. I disagree with the inclusion of abstractions like “Taking a camel train across the Sahara” – it might be a wonderful experience but certainly not a “World Wonder” in the accepted sense.

Here’s a few genuine wonders which somehow escaped inclusion -

Best man-made -
Venice, esp St Marks Square (my personal numero uno)
The Pantheon – worlds oldest intact (hollow) building
Jerusalem old city
Pompeii
St Petersburg
Isfahan

Best combination of scenery and man-made -
Santorini – both for the stunning views and the clifftop village of Oioa.
Lake Bled, Slovenia – surely the most sublimely beautiful lake in the world?
Cape Town and the Cape Peninsula takes a lot of beating too, but I’m obviously biased

Anthony, Cape Town,

Uluru or Ayers Rock? My, my, the Australians are getting sensitive after having slaughtered their aborigines! You have stolen a nation from them, whats in a rock?

James, NY

James Marshall, New York, US

How is it the kids I teach have been on safari but can only name three counties in the UK? Don't suppose Shakespeare or Mozart ever peered into an active volcano -lives 'not lived' I wonder?

emily , york , UK

Arsenal's Emirates Stadium in north London. Specially when Thiery Henry is playing..

C. KOSE, Kocaeli, Turkey

No Great Barrier Reef.......surely an omission ?

John Jago, Sydney, Australia

Meteora, Greece. If you've been there, you know why it should be on the list. Las Vegas? I've been to all 50 states and most major cities in the U.S., but I've never been to las Vegas and I hope it stays that way.

The cheap shot at Arizona is completely unjustified, but we Americans have come to expect this sort of thing from the British media.

Ross, Lander, Wyoming

What about Hagia Sophia, the 1600 year old Byzantine Cathedral in Istanbul? If you are looking for a cool church, this is the one. 300 meters from it, one of the coolest mosques, the Blue Mosque comes as a bonus. Two big birds with one stone!

Emre Eldener, Istanbul, Turkey

Ross, a otwn on the west coast of New Zealand is a truly remarkable place.
My wife loves the three Rs- Rio de Janeiro, Rome and Ross.

Gene, Sydney,

I thought that the basis of the wonders involved some human input and by doing so they were distanced from beutiful landscapes which metrely exist. My personal experience of those I have been fortunate to visit is :
The most beutiful man made prize for me goes to either the Taj or the mask of Tuten Kahmun.
The Acropolis missing? The cradle of western denocracy you must be joking!
Great Wall amazing feat of human endeavour awe inspiring, but Forbidden City, why?
No 9 "Valencia stick your head between your legs and wistle up your Barcelona"! Where is Stone Henge?
Petra, Chichanitza etc. well worthy.
What about a vote for the Burge Al Arab in Dubai for a modern day wonder?

Keith Hirst, Atlanta, Atlanta, USA

Clearly you've never been to Singapore.

Jack Sparrow, Capt., Yokohama, Japan

What about Barranca del Cobre in Mexico ... 5 time larger than the Grand Cayon but wihout all the hype.

Liliana, Horb, Germany

How about Ngorongoro crater in Tanzania! Its the most beautiful safari park in the world! Also the Islands of Zanzibar......its just A-mazing...the sunsets and sunrise...the beaches..words cannot describe!

Hendrik, London, UK

And what about Moonee Ponds ? Great shopping in Puckle Street.

ross, Paris,

Monument Valley, Utah

Charlton Griffin, Thomasville, GA

Well, I guess the largest concentration of fresh water in the world should be mentioned. I would think so, but alas no one seems that interested in all natural wonders.

We'll just keep out little Michigan secret to our selves, the only state where you can see three of the fresh water miracles all in one day. Never mind that we have other wonders. Just because it has been out done by newer construction, doesn't take anything away from the Mackinaw Bridge. No, we're not as trendy as Las Vegas, but as most Michigan snow birds will attest, Las Vegas has nothing on South Florida. That's why many of those snow birds are choosing Texas instead -much more relaxing!

Nope, we're just too hopelessly mundane sitting here between three lakes that combine to be bigger than some seas.

Lorna, In the Middle, Michigan

Iguazu falls on the border of Brazil and Argentina has to be on there it's incredible, however, the Itaipu dam just down the road is uninspiring. Lago Espejo in Argentina is amazing. Isay swap Las Vegas for Rio or Buenoa Aires any day!

James Morris, Blackpool,

What about Paris- the most visited city in the World. Surely it must feature...

Sarah Pank, Paris, France

If you were going to mention Nevada, then the sight to see there is certainly Lake Tahoe. It is a bit touristy, but the beauty of that cold, blue lake cannot be overstated. It is truly magnificent.

In the South, how about just the Great Smoky Mountains in general? These beautiful, rolling hills are a real treasure.

Although I have never been to Austrailia, I cannot imagine leaving The Great Barrier Reef off such a list. The diversity of life it hosts is enough by itself to warrant a mention, to say nothing of the beauty and sheer scale of it!

Amy, Decatur, Alabama USA

You should really do some research on what The Sagrada Familia is all about before writing jiberish! Not everyone is an architectural critic and you certainly arent. You must be educated in architecture to be one. One of the wonders should be how you came to write this piece.

James, Los Angeles,

One of the most beautiful places in the world is Gros Morne National Park in Newfoundland, Canada. It is truly one of the best kept travel secrets.

Banff and Jasper in Canada's west are truly gorgeous too! Obviously, as a Canadian, I felt a little jilted by the 25 picks!
Come to Canada and see true beauty!

Pam, Toronto, Canada

What about Sigiriya in Sri Lanka? In the same vein as Macchu Pichu, was 'lost' for so many years. A wonderful place with a frightening history, a scary climb with a tremendous reward at the top.

Jason Preston, Leeds, UK

Inspiration Point, Bryce Canyon, Arizona. The beauty of this place made me cry. if you ever get the chance to see sunrise there, do it. I knew there was a God after seeing the sun rise there.

Jenny Taylor, Manchester,

What about Sydney Harbour,probably the most beautiful
natural harbour in the world.
Australia,the largest island in the world.
The polar ice caps.

David Nigel Braham, Milan, Italy

Las Vegas? A joke. Go to Macau or Bangkok for an unspeakable time. Hell, there's more off the wall temptation in Kobe than Vegas. But I guess we cant expect the cubicle-dwelling, Middle-aged Hobbits of America to find a real den of Mordor, can we? Sure, it may be the "wildest" place in the US, but we're supposed to be talking about a WORLD list, mmmkay?

D, Kobe, JAPAN

Whitechapel, East End

CG, London,

Glad to see Salar de Uyuni made number one, one of my favourite places that few people have visited. Angkor Wat and Macchu Picchu are incredible too although after 4 hours trekking my legs could barely carry me around it. Have to agree with a few other comments that Iguazu falls, Yosemite and the great barrier Reef should be up there. I'd also add Valle de la luna in San Pedro de Atacama in Chile - the most incredible sunsets. btw i loved arizona.

Fiona, London, England

The islands off El Nido in Palawan, Philippines. Spell bindingly beautiful nature in the rawest, most dramatic sense.

Tony McFadden, manchester,

What about Sydney Harbour,probably the most beautiful
natural harbour in the world.
Australia,the largest island in the world.
The polar ice caps.

David Nigel Braham, Milan, Italy

The Sequoias (trees) of California...Muir Woods, Sequoia and Kings Canyon National Parks...the oldest living things on earth, us (man) notwithstanding...no wonder!?

Bert Lindsey, Prague 2, Czech Republic, Europe

Can you explain your comment about Arizona? If you think that large crack in the ground is the only thing worth seeing here, then you need to get around more.

Tom, Scottsdale, Az

Niagara Falls!!!!!!
And the best part of it is in Canada - Horseshoe Falls!!!!

luke fisher, Ottawa, Ontario

Maybe the title's wrong - should be something like "25 best ways to increase your carbon footprint" . If you dump the middle-class, back-packing, gap-year, talk-about-it-at-dinner-parties stuff it's pretty clear that the main wonder of the modern world is the internet. I can go anywhere for free and find out more about it than you can on a bus full of chickens. All that I lack is interesting toilet facilities and the risk of a variety of nasty diseases....'Scuse me - off to Ulan Bator for lunch.....

Ceecee, Newcastle upon tyne, UK

What about Niagara Falls, Stonehenge, Newgrange, Mt Everest, and many others. I think that this list really just wanted to put out places that are popular to visit, that is why Vegas is on there. The only thing that I can think of in Vegas would be the architecture, you can truly see the great sites of the world recreated there.

David, Erie, PA, USA

Craig, sydney - you seem like a very nice person........

iain, norwich,

Sir. The biggest issue has been left out and this may never come back again. Grab it now

THE WONDER OF THE WORLD.

Arctic melting and the Pluto kicked out to be replaced by the new one with H2O, we hope

Firozali A.Mulla MBA PhD, Dar-Es-Salaam, Tanzania

Why isn't Anfield included in this list?!

Antony, London, UK

How sweet. Catering for a lot of different people by quoting so many wonders from so many different countries, especially the wonders of Las Vegas. So cute, in this politically correct world, but surely you forgot the sites of LA and the amazing thrill of roller coaster rides at Disney Land, both worthy of a top-10 spot seperately on the list. Oops, I almost forgot the wonder sof fast food.

Certainly most of the sites are worthy of mention but it amuses me that Uluru or Ayers Rock made the list ahead of Mount Augustus which is actually the largest rock in the world ahead of Uluru at number 2.

Also, what about the Great Barrier Reef in Queensland Australia which is about 2,000 miles long and can be seen from the moon. I guess Las Vegas is just so much more spectacular. Thank you for adding to my cultural diversity and wealth of knowledge.

Craig, Sydney, Australia

As an Aussie reader I just have to say that calling it Uluru is not 'PC' but simply using the name that Aussies now use and have done for at least the last 10 years. Which is, I guess, kind of the point of the list.

Amy, Melbourne, Australia

I don't think we should get too het up - this appears to be solely based on the opinion of the staff in the office at Rough Guide! ...(and for a start anyone who's anyone reads Lonely Planet!). We could all write our own list and they would all be completely different...mine would be topped by climbing Half Dome, Yosemite, kayaking on Doubtful Sound, NZ, snorkelling Great Barrier Reef, Aus, eating icecream on the banks of Emerald Lake, Alberta - not to mention the countless beautiful places in England - Dartmoor, Exmoor, Lake District etc etc....

Rosie , Kingston, England

The Rice Terraces of Banaue in the Philippines gets my vote - built 2000 years ago and still there today, an amazing feat of man and nature.

What about Luang Prabang, Laos? Possibly the most charming place on the planet!

Julia D, Clapham, London

What About BURMA's ancient city of PAGAN and 3000 buddha temples?????????

DR M Z AUNG, London, UK

Please. Kennedy Space Centre in Florida, home of the greatest achievement in the history of humankind: the Apollo missions to the Moon. A Saturn V is on display there, and you can marvell at the Vehicle Assembly Building (3.75 times the volume of the Empire State Building), and the crawler transporters (18,000 pounds fully laden with the space shuttle, 42 feet per gallon).

James, London, UK

Yes I agree with the other commenters that Arizona was unfairly tarnished. We drove on a family road trip through much of Arizona a couple years ago and we were glued to our windows like it was a TV screen. Something different from top to bottom there.

In the north there are the mountains and the weather is COLD in August, which was surpising for us. That's because the elevation is so high there. The trees are tall lush pines and the grass is very green and you feel like you are in a Bonanza episode. Around Flagstaff we see that they have skiing.

The center part has the tall stoic cactuses everywhere you look in the lonely dessert and the towering mesas flank you in the distance. Phoenix is a glitzy modern city where everyone has cactuses in their yards and students pack into Jeeps in the main drags.

The south part has the rolling hills on the Mexican border and quirky mining towns such as Bisby. There's so much more to say about it - but trust me it's an amazing state.

Claudia, Atlanta, USA

How on earth, is the Parthenon not in there? I cant seem to think of another building with such artistic excellence built 2500 years ago and still standing, despite numerous invasions and bombings!!!! Las Vegas Temptations? I ve been to Vegas, its not temptations its entertainment for those searching for the banal

Thanos, Halifax, UK

La Sagrada Familia in Barcelona takes a place in the list with justice. Is absolutly monumental and breaks your heart to know that the plans were destroied before conclusion and after it's creator, the genious Antoni Gaudi, died. So we don't really know how Gaudi wanted to finish it. Too bad the Cathedral of Toledo is not included on the list. Spain is, along with Italy, the most beautiful country in Europe and the list of monumental places to see is endless. In Italy, Saint Peters Cathedral is a wonder alond with the Sistine Chapel. The escavations in Pompeii are a must if you enjoy to visit unique places and so is the Duomo of Milano and the city of Florence. Going back to Spain, El Valle de Los Caidos is also monumental, along with the Monasterio del Escorial and the Cathedral of Santiago de Compostela with it's "botafumeiro". The list goes on and on and on.The Alhambra and the mosque of Cordoba are also good points of attration in gorgeous Spain, but I would say they are minor ones

Fabio C, London,

I cant believe the Masaai Mara in Kenya is not on this list its an unbelievable place you can watch lions hunting in the wild up close and personal............................tremendous experience, very nice weather too.

Yhe wildrbeest migration there is the most brilliant, outstanding and stunning sight you will ever see in this earth

PK Moses, Manchester , UK

*The Borobudur temple in Java. built in the 700s, this is the largest Buddhist temple in the world. Constructed around a hill, it relates the entire Buddhist experience in stone carvings, mile after mile of them, until you arrive at the open top sections, where boddhisattvas sit inside stupas, teaching, having renounced Nirvana to do so. And topping everything, the immense and empty stupa representing Nirvana itself.
*The Hagia Sophia Cathedral in Istanbul. Before islam this was the largest Christian church in the world, and so aweinspiring that not even the fanatical Turks dared touch its mosaics. They forbid it to be used as a Church, but it is still magnificent.
*The Silk Road, from Xian in China to Palmyra in Syria. One immense network of trade that bound the world together as never before or since.

Susan Scarcella, Sydney , Australia

what about stonehenge??

i know it's a bit run down but it's been there for the best part of four thousand years. maybe you have to see it yourself to appreciate it properly.

the sagrada familia is an eyesore with novelty value, and will only look slightly better when the cranes are finally gone.

Brian, Culiacán, Mexico

I cannot believe that the Itapau dam is included yet just twenty minutes from it are the Foz de Igauzu waterfalls which span the Argentina Brasil boarder.
These falls are 2.5 miles wide and and it is a 2 day trip to see it all from both countrys.
The Itapau dam is just a time filler if you have an extra day.

John Boyle, Buenos Aires, Argentina

Nothing in New Zealand worth listing?

My particular favourite, among many, is looking from the top of Treble Cone near Wanaka, South island. Next would be Fox Glacier.

Give us a break and come down to the bottom of the world some time. Or at least watch Lord of the Rings.

Frank , Sorrento, Western Australia

So what's wrong with Arizona? Go there most years, never to the Grand Ganyon. Only an hour or two from the North Rim you can be in Zion or Bryce Canyon (Utah). Same time from the South Rim and you are in Sedona (Az). Both places utterly stunning to European eyes like mine.

But the most wondrous? Without question, the Canyons de Chelly and Monument Valley, both on the Navajo reservation, Arizona.

Yonze, Victoria BC, Canada

Been to 5, but what about the local bars, food, and people. That is so much more fun then the museums and tourist traps.
I hate standing around with pale middle aged American, German, English, Japanese tourists and taking snapshots.

I'll be down at the local cafe or bar, thank you. I love Eastern Europe.

Damien, Currently San Diego, American Expat in Waiting

I have visited many places on the list in my travels, and I think there are a few serious omissions that come to mind. Yellowstone National Park in Wyoming, Bryce Canyon National Park in Utah, and the Giant Redwoods of California are truly surreal and awe-inspiring in more ways than one. Since we moved to the US from the UK several years ago, I have come to realize that the amazing diversity of natural wonders that the US is fortunate to have are never seen by most visitors in their haste to play blackjack in Vegas or visit Disney. The majestic grandeur of the USA is in the National Park system. Come on over and see what I mean!
Kirk Lalwani, Portland, Oregon

Kirk, Portland, Oregon, USA

If you want to look down the spout of an active volcano, try Aso-san in Kyushu, Japan. At the bottom is a boiling lake of sulphuric acid, and occasionally a whiff of it comes up....

It's on the tourist route, by the way.

J F James, Beppu, Japan

I nominate Orpington. I'm sure Plato would have gone out of his way to see Orpington had it existed then. They 'ad nuffin' like it in Greece. Still don't. Dunno why.

Jonathan, London,

Sagrada Familia is not even the top "wonder" in Spain. Granada's Alhambra or Cordoba's Mezquita beat it by a mile.

Pau, Gerona, Spain

Snowdonia, Wales. Not to sound too trite, but Great Britain has plenty of wonders as well. And nothing really beats the Snowden Mountains in Northern Wales for true magnificence. Plus you add the Merlin Legend and it's definitely something truly breathtaking to behold.

And Portmeirion in Wales is nothing to scoff at as well. Truly beautiful, highly recommended.

Nick Zbu, Ann Arbor, Michigan

Angel Falls, nearly one thousand metres of pure water falling down from a table mountain in the south of Venezuela.

Where is Uluru?

Brooks, Munchen, Germany

What about Trompetersteeg, Amsterdam? Many readers will agree that this is perhaps the greatest wonder of the world!

Cory K'sure, London, United Kingdom

Why is the Great Barrier Reef on the list? I know it is endangered by excessive tourism, but it is the largest living thing on Earth, and viewable from space....

Jack Smith, South West London, UK

Ngorongoro crater is by far the best place I have visited, its like the Garden of Eden with multitudes of animals,birds flowers trapped in time.

jim ferguson, leatherhead, england

"I heartily approve of this list’s inclusion of the entire Amazon, and the Sahara. If we’re ticking boxes then there’s a good glacier, too, a questionable mosque – but no cathedral (not cool)"

I understand No.11 The Sistine Chapel, Rome is located in a rather famous Cathedral - if only I could remember the name!!!

Pots, Luton,

<I was about to say that Uluru in Australia, which I’ve never heard of, sounds fantastic – until I discovered that they mean Ayers Rock. Oh, spare us this PC stuff, Mr, Mrs (or Ms) Rough Guide. >

If we want to call our rock Uluru, then we will do. Who are you to say we can't? Not PC at all. That's its name.

Frances, Ballarat, Australia

plettenberg bay just a bit of coast a lot of countries have similar coasts. The really wonderfull sight might be antartica theres a lot of volcanoes down there and aparently hot springs that you can swim in which is not hat you would first expect from a cold place. I just love the cleaness of the place and the isolation. there are also strick internationally agreed upon quotas for how many people can go there to limit the environmental impact on the place, so going there is a real privelege. And of course theres the penguins.

Gordon, Joberg, South africa

" but no cathedral (not cool)"

What do you call Sagrada Familia. And how do you not consider it a wonder. With all of todays technology it has been under construction for almost 130 years and still needs a minimum of 60-80 more to be completed. Just because you dont like an architectural style does not mean it is not worth including in the list.

David, Anchorage,

Uluru isnt being PC - thats its name used thousands of years before anyone called Ayres ever existed. Might still not reach most peoples radar but there were people in Australia long before the English wandered this way

Like the lady said - write a travel piece not some ill judged comments on politics or place names

jce, Sunshine Coast, Australia

I expect higher quality pieces from The Times, a rather weak attempt at humor I would say. I would also contend that the canyons of New York are more impressive then Las Vegas, any day.

J. Holden Gibbons, Shaker Heights, Ohio

Is this list "things to see" or "things to visit"? If it's "visit" then the Sagrada Familia shouldn't be there. It's lovely and impressive to look at from the outside, but is nothing but a building site on the inside - plus they charge you 10 euros to get in.

As for "A life that has not included peering into an active volcano cannot be called a life", well, a life that includes peering into active volcanoes can be called a short life!

Miles, Dublin, Ireland

If this turns into a contest of aesthetics, e.g. natural and/or man-made beauty, then this argument will simply never end as aesthetics are thankfully an entirely subjective matter.
I have not (yet) seen all of the 25 listed above, but I can assure you that I have in my top 25 a few destinations not included in your list. I shall not mention where or what is included in my list to avoid any subjective arguments which are down to a matter of taste, but I do thank whoever put the list together for the inspiration for some future travels.
Surely half the beauty is in the travel and challenges experienced, all of which cannot be captured in a picture.

Chris, London,

Shame about Arizona??? What exactly are you implying? Sedona, Moment Valley, Tucson, Tombstone, Lake Havasu, Canyon de Chelly, the Hopi/Navajo nations, Sonoran Desert.......

You need to get out more. Arizona is a beautiful place.

Scott, Phoenix,

Bryan - They haven't missed Uluru; it's second on the list hon : ) A magical place indeed!

Mavis, Cheltenham, UK

Surely Persepolis, Iran should be on this list?
Admittedly not in its prime these days, but undoubtedly a marvel of human achievement.

Bonnie, London, England

What about Niagara Falls Canada! Thats certainly a wonder! People come from all over the world to see it.

Cheers

Kevin, prince george, Canada

Wait a minute.. do you just complain that the Segrada Familia was on the list, then complain that they didn't include a cathedral?

Alan Heckman, Manchester, UK

None of the nominees have been to Plettenberg Bay...? It would truly be a wonder to see one of the Easter Island giants on a tourboat in South Africa

Sam, Boston, USA

The Sagrada Familla an "elaborate architectural joke"???

It IS a masterpiece (or will be in 50 year's time!). YOU may find it "naff" but at least it's not like all those depressing Victorian monuments with their hideous gargoyles.

Hooray for Gaudi! Someone who belived that religion could be a celebration as opposed to a chore!

Hannah, Leamington, England

What about Serengeti National Park, Tanzania, during the annual migration? I'm amazed that wasn't included in the top 25.

Fleabea, Melbourne, Australia

A few other sights / activities that I would rate very close to the top of the list!

Wolf Creek Meteor Crater
The Bungle Bungle
Silfra
Cape Horn
Swimming with Whale Sharks off Ningaloo Reef
Crazy Basils in Red Square
Gaudi's Cathedral in Barcelona
The Northern Lights
The iron ore mine at Mount Magnet
The Stairway to the Moon from Cable Beach

Simon Wilson, Farnborough, UK

Kerela in India is amazing - they call it the Venice of India. They have an amazing boat race there every year - well worth a visit.

Elizabeth, London, UK

Volcano? Try Guatemala for its seven active ones, in addition to the Maya ruins.

Carlisle Johnson, Guatemala City, Guatemala

I have vistied 8 of the destinations and while they are all worthy nominees the Iguazu Falls in Brazil/Argentina/Paraguay were a far superior experience.

Stuart Hardy, Nottingham, England

"I agree about Arizona’s Grand Canyon (nice canyon – shame about the state)."

What's wrong with Arizona?

Arizona is amazing. The grand canyon is cool, although it might be better with out the busloads of daytripping tourists who are shipped in to look over the south rim and take a picture, then leave, thinking they have seen it.

But Arizona has so much more! Monument Valley. The Petrified Forest. Sedona. Meteor Crater. Arizona has some of the most beautiful desert scenery in the world. It has ancient abandoned cliff dwellings. It has the oldest continually occupied city in the world! It has a legitimate claim on a fascinating history of cowboys and gunfights and mexican border culture and indiginous native american tribes. It has 320 sunny days a year.

When i lived in Arizona, my apartment had an orange tree outside the door. I had access to a swimming pool. Actually, it looked a whole lot like the places in Spain where British people go on holiday. And it cost me £200 a month!

Alan Heckman, Manchester, UK

"I was about to say that Uluru in Australia, which I’ve never heard of, sounds fantastic – until I discovered that they mean Ayers Rock. Oh, spare us this PC stuff, Mr, Mrs (or Ms) Rough Guide."

You're kidding, right? Just because you are ignorant, doesn't mean everyone else has to be.

buzzgirl, Sydney,

"Nice Canyon--shame about the State"? But Victoria Falls (very impressive, as well) doesn't get a 'shame about Mugabe'? Excuse me, what is wrong with Arizona? Are they starving their own people? Are they sending out frenzied mobs to murder people? Trust me, I'd rather live in Arizona than Zimbabwe and I have never and would never vote for 'W' Bush.

Write a travel piece, not an unjustifed attack on America

Elizabeth, London,

If you want really awesome salt flats - complete with "chimneys" of steaming mineral vapor - then try Djibouti. Air France goes there once a week, and the reefs are awesome too.

Deedee, Buffalo,

Las Vegas!?! What a dump! Trollops and traffic, yuck... The Sistine Chapel is remarkable, the whole Basillica is however utterly eye-popping. What, no Yellowstone National Park? Geothermal wonders combined with the staggering spectacle of North American mega-fauna, not to be missed.

Rob Cordery-Cotter, LaPorte, USA

Never heard of Uluru? What planet have you been on for the last 25 years? It's been the official name since the land was returned to it's original Aboriginal owners in the 1980s.

Bryan Miller, Auckland, New Zealand

Obviously none of the nominees of the list have ever been to Plettenberg Bay, or indeed South Africa.

Tony Raponi, Swanwick,
