Arecibo Observatory

This observatory/telescope-thing is huge, and probably an interesting place to visit. Seeing this massive structure alone would likely be neat, but the surrounding Puerto Rican mountains and forest might also be a nice addition. I think there's a visitor center at the observatory, too!

Two Lovers' Point

Guam's outlook point called Two Lovers' Point seems to have quite a nice view. Apparently, the waves below sometimes form a heart-like shape, which is kind of cute. The views of the island from here are likely the main attraction, though.

Kalaupapa

The Kalaupapa Peninsula of Molokai is interesting for two reasons. One reason is its interesting historical background as a leper colony. Another reason, probably less known and appreciated, is its status as the smallest county in the United States by some definitions (maybe).

Also, this place is tough to get to, and views of the cliffs to the south from here I'm curious to see.

Halawa Valley

Halawa Valley is a very green (forested, jungled, or something) valley in eastern Molokai. There are some impressive waterfalls visible from here.

Dry Valleys

The Dry Valleys of Antarctica look quite extraterrestrial, y'know, for a place on Earth. It appears to be basically some of the few (or only) places on Antarctica that aren't covered by snow. The mountains look beautiful, and walking on the dry surface here might be an amazing experience. There are also bodies of water such as lakes, which might behave strangely depending on the weather when one visits.

Chimanimani Mountains

These mountains have waterfalls and are themselves fairly interesting to look at, I think. The colors here, along with the grand terrain, might make for some excellent vistas.

Great Zimbabwe

These ruins are apparently famous enough to name an entire country after them. I assume they're historical and big.

Halong Bay

Halong Bay may be Vietnam's most famous natural wonder. I think it even got featured on that big poll of natural wonders recently.

So many islands, mountains, peninsulas, and water to look at here! (also "Bai Tu Long Bay" to the northeast might be a good less touristy alternative which also looks impressive)

Cerro Autana

Cerro Autana is an impressively-shaped tepui in southern Venezuela. The colors and shapes here look like a masterpiece of creation.

Yasur

Yasur is a famous volcano, very active I think, on the island of Tanna in Vanuatu. The fiery colors of a nighttime eruption might be quite a neat sight, though I wouldn't want to go into too much danger.

Punta del Este

"La Mano", a sculpture representation of a hand, or something, is a famous place in Punta del Este, Uruguay. I understand this is a small, insignificant, weird thing to list on this list, but... here it is.

Another, bigger, place to visit around Punta del Este is Casa Pueblo, which reminds me of Santorini in Greece. I kind of like the way it looks in pictures better in some ways, though, I think, maybe.

Saint Kilda

Saint Kilda is an island, which I think is included in the Outer Hebrides. It's got those lovely-looking green hills, and some old stone structures that I assume are very, very old. And even if they're no,t they look really neat on this isolated-like island. There are totally some great views available here, I think.

Giant's Causeway

The Giant's Causeway is a very famous location in Northern Ireland. It's a curiosity of nature, with hexagonally-shaped pieces of rock or something. Hmm, it actually does look kinda cool! Also, the visitor center/centre looks kinda cool too.

Fujairah Fort

In Fujairah, there is a large old fort structure, and much of its history seems unknown. It was recently restored, and it looks kinda nice.

Hoverla

Ukraine's highest point, Hoverla, is part of the Carpathian Mountains. It's covered with green (or white in winter, I suppose), and there are bright flowers around here as well. The area near the top looks especially beautiful, with rolling topography and such.

Cape Fiolent

Ukraine's Crimean Peninsula's Cape Fiolent's scenery's viewing opportunities look excellent. The rocky coast it's part of looks like a neat place to walk around.

UPDATE 3/23/2014: Might not de facto count as Ukraine anymore.

Rwenzori Mountains

The Rwenzori Mountains appear to be quite a unique mountainous area. The African plantlife here looks fantastical, and the snow here would possibly be considered misplaced in the jungle areas of Africa. There are waterfalls and rock features I think, and overall it looks like a beautiful place.

Murchison Falls

Uganda's Murchison Falls look pretty, and they seem neat enough to have a national park named for them.

Funafuti

Funafuti is the main atoll of Tuvalu, hosting its capital and its largest population (I think). Tuvalu's main government building looks quite nice, and the great length of the islands' large "arms" might be an interesting journey.

Darvaza Gas Crater

Near Darvaza in Turkmenistan is a crater that is known for being quite a fiery sight at night. Apparently, there was a gas accident here a long time ago, and the resulting burning hasn't yet stopped.

Cappadocia

Cappadocia, Goreme, whatever. It's got very odd terrain, and some home seem to have been built out of the very odd terrain as well. Interesting enough for me, I think.

Tamerza

In the area of a place called Tamerza in Tunisia are a few nice-looking places. There is a canyon in a nearby place called Mides, and an oasis in another nearby place called Chebika. Tamerza itself, appearing to be in a gorge of its own, also looks interesting.

Mont Saint Michel

Mont Saint Michel is known for a castle-like structure on an elevated piece of terrain on a scenic peninsula area. Not sure exactly what it is, but it really does look cool, and I probably wouldn't be disappointed at the way it looks.

Delhi

This was originally a "Red Fort" post, but I've since found out that there's other neat stuff in Delhi. There's the Red Fort which is large, impressive, and reddish. There's the tomb of Humayun, one of those Mughal emperors (learned that from Britannica). There's the Parliament building, or the Lok Sabha building, or the Gandhi stuff like Raj Ghat, or something. There's this mall-like thing which features the Presidential building, a big spire/column, and at least one museum it seems.

Delhi seems to be quite an important city, and there seems to be a lot of neat stuff to look at here.

Great Blue Hole

The Great Blue Hole is pretty much that. Off the coast of mainland Belize is either an island or an underwater reef or something with a really interesting dark circular spot, which I imagine is an odd deeper part of the ocean. Not sure who I would view it, but it would be quite a sight, I think.

Potala Palace

This Tibetan palace is quite a famous place. If I remember correctly, this was the historical residence of the Dalai Lama, some big figure in Buddhism. The palace looks neat though, on its own little mountain or something, and big too.

Faille d'Aledjo

This is a really weird spot, I think, but it's not totally boring and it's in Togo, a little country in Africa. Sort of like a roadside stop in the U.S. Basically, it's a tall, very narrow-looking gap in a rock that a road's been built through.

Cape Fatucama

Cape Fatucama is a place in Timor-Leste that features a peninsula, with a hill that is topped by a large statue called Cristo Rei. From this place, and perhaps others in the cape area, are likely great views of Dili and other nearby features. There may be a chance to see Indonesia from here as well.

Prachuap Khiri Khan

Prachuap Khiri Khan, I think, is a city or something by the coast of the Gulf of Thailand. Its bay scenery is the main thing I found interesting, with some tall hills/mountains/rocks on islands and peninsulas. Also kinda neat is its location on one of the very skinniest parts of Thailand (like, less than 10 miles across from Myanmar to the ocean).

Ayutthaya

Ayutthaya was the capital of Siam hundreds of years ago, perhaps. It was apparently destroyed, but the ruins are still there, looking interesting.

Sukhothai

Sukhothai was the capital of ancient Siam hundreds of years ago. Its buildings today look really old and interesting architecturally.

Shwedagon Pagoda

Not interested in this for its religious significance or anything. It just big, golden, and noticeable.

Chichen Itza

Yes, there are likely better and less touristy places like it, but it does look famous and cool. Big stair-steppy pyramid. yay.

Acropolis

This is possibly Greece's most famous ancient landmark, and it's likely noticeable at Athens's Mars Hill. I think Paul did stuff here, too. Not sure.

Fallingwater

Fallingwater is a famous house or something designed by Frank Lloyd Wright in Pennsylvania. It has a unique setting on a river with waterfalls, and its shape and design looks appealing as well.

Aletsch Glacier

Aletsch Glacier is apparently the largest Swiss glacier. I imagine it's also easier to visit than other glaciers of the world. There's a good view it seems from some mountainous lookout points to its south, and likely plenty more.

Geneva

Geneva is a popular city for international events and headquarters, it seems. Among interesting places here are CERN and the city's tall water(?) fountain.

Ronda

Ronda is a Spanish city with really cool natural features, particularly the famous gorge depths. The city also looks architecturally pleasing to look at, and the famous bridge over the gorge seems quite impressive as well.

Lake Bled

Lake Bled in northwestern Slovenia has some serious romantic potential. There's even seems to be an island in this lake with a castle on it. Or maybe it's a church. Still, serious romantic potential in this area.

Also the nearby Vintgar Gorge seems to have a very lovely walk along a river in a forest canyon.

Singapore

Singapore's got weird and modern buildings, and probably some interesting culture due to all the different groups that seem to make up its population. Might be fun.

Freetown

Freetown and the surrounding populated area looks huge, but also seems like a fascinating place to explore. There are natural features like a cape and beaches and some mountains, as well as plenty of man-made structures, some of which are likely interesting (perhaps government buildings and lighthouses). The culture of this city also could be interesting to learn about.

Piva Lake

Piva Lake, and the mountainous rim above it, looks very promising as a beautiful place to stop and look.

Tara River Canyon

The canyon which contains the Tara River is huge, green, and looks amazing.

Ilhéu das Rolas

This island in São Tomé and Príncipe is small but interesting due to its location right along the earth's equator. There appears to be a monument dedicated to this interesting quality, and the island itself seems pretty scenic anyway.

Mount Titano

A famous feature of San Marino, Mount Titano looks like one excellent place to tour. The view from here is likely excellent, and the castle-like structure on top looks lovely.

Pitons

The Pitons are two enormous volcanoes on the southwestern coast of Saint Lucia. They look really impressive, especially being so close to the coast. I'd likely be interested in seeing the Gros Piton or the Petit Piton from multiple angles. From the sea, or from the other mountains, or from the beach, the Pitons probably look amazing most, if not all, of the time.

Brimstone Hill

This hill on the island of Saint Kitts (aka Saint Cristopher) has a historic fortress on top with gorgeous views of the sea, the island, and other islands. You can even see the Netherlands from here (okay, a Caribbean island that's under Dutch independence)! The fortress itself is also appears to be a nice place.

Valley of the Geysers

In a volcanic region of the Kamchatka Peninsula, there is an area known as the Valley of the Geysers. The pictures of this place capture some amazing views, and it appears to have been a natural wonder of this planet. Apparently, a landslide or something here happened recently, so I'm not sure if this place has been affected much since then. Still, the land looks beautiful.

Kizhi

Kizhi is an island in western Russia that includes an architecturally complex building that might be called the Transfiguration Church. This building has quite a number of those "onion dome" thingies.

Lake Baikal

To my knowledge, Lake Baikal is the world's deepest lake. It's probably Russia's largest and most famous lake as well. There is mountainous scenery right next to the lake, with abundant plant life as well.

Doha

Doha is the capital of Qatar, one of the wealthiest nations per person in the world. The skyline alone looks pretty impressive; it might seem really impressive at night. This place also seems to be trying to look its best for the international community, with their hosting of the World Cup and their bids for the Olympics, and other events they're likely working on.

Bom Jesus do Monte

This church in Braga features a very interestingly designed stairway that looks pretty cool.

Porto

Porto looks like one of Portugal's prettiest cities.

Lisbon

Lisbon is a historic city that's the capital of Portugal. Sights here include a castle, a place called Belem, and a statue called Cristo Rei.
