The Richat Structure

Mauritania, Africa
Also called the Eye of Africa or the Eye of the Sahara, this is a type of geologic feature characterized by an eroded volcanic dome. It is 25 miles in diameter and, despite parts of it being around 100 millions years old, its existence was not well known until the 20th century.

Dragon's Blood Trees

Socotra Island, Yemen
This island, part of an Indian Ocean archipelago, is home to some of the oddest-looking plant life found on Earth: the Dragon's Blood Tree. According to Atlas Obscura, the island is thought by some to be the original Garden of Eden "due to its isolation, biological diversity, and the fact that it is located on the edge of Yemen’s Gulf of Aden …"

Yellowstone National Park

Wyoming and Montana
There are tons of otherworldly sights to be found in America's first national park, but perhaps none quite as massive and dramatic as the many-colored Grand Prismatic Spring.

Zhangjiajie National Forest Park

Hunan Province, China
Towering pillars like these are the most notable feature of this already-stunning park, which was designated China's first national park in 1982. It is part of the larger Wulingyuan Scenic Area, a UNESCO World Heritage Site. 

Marble Caves

Blue Marble Caves

Patagonia, Chile
These cerulean caves have been carved by some 600 years of waves crashing into them. Not easy to get to, visitors must fly to the Chilean city of Balmaceda and then drive 120 miles, including over some remote dirt terrain, before finally boarding a boat to tour the caves.

Buzludzha Memorial

Kazanlak, Bulgaria
While it might look like something out of an alien movie or "The X Files," this saucer-shaped structure — the interior is shown here — is actually a monument to communism. It's been closed since the late 1980s, but Atlas Obscura notes that "plans to preserve and restore" the site are underway.

Whale Bone Alley

Siberia
Visitors to Russia's Yttygran Island will find hundreds of mostly jaw, rib, and vertebrae whale bones, many aligned in rows and thought to have been placed by a collective of native tribes around six centuries ago as a place of worship and ritual.

Lake Hillier

Esperance, Australia
A lake the color of cotton candy? Yep, the 600-meter-long Lake Hillier's vibrant pink color is made even more dramatic by its proximity to the sparkling blue ocean it lies near. According to the lake website, it's color still isn't fully understood, but "most suspect it has to do with the presence of the Dunaliella salina microalgae."

Giant's Causeway

Northern Ireland
As the only World Heritage site in Northern Ireland, Giant's Causeway is home to unique column-like rock formations made some 60 million years ago. In all, there are more than 40,000 columns that are packed so tightly and shaped so regularly that they almost look man-made. You can find out more about their geologic history here

The Gates of Hell

Karakum Desert, Turkmenistan
This constantly burning part of central Turkmenistan, formally known as the Darvaza gas crater, sits above the largest natural gas reserve in the world. It's man-made, created in 1971 after a drilling rig inadvertently punched into the natural gas cavern, creating a 230-foot wide hole. The Soviets set the escaping gas on fire, thinking it would eventually burn itself out. Fifty years later, they're still waiting.

Abandoned Marx Generator

Near Moscow, Russia
This generator looks like a scene out of a sci-fi movie, but it's actually a largely abandoned structure constructed in the 1970s by the Russian Electrical Engineering Institute, according to Atlas Obscura, meant to test lightning insulation.

Vatnajokull Glacier Ice Caves

Iceland
One of nature's great works of art, Iceland's ice caves reform each year in the fall and are safe to visit from about November to sometime in March with a tour guide. Each is entirely unique, but some of the most extraordinary are the "Crystal Caves." in Skaftafell National Park's Vatnajökull Glacier.

Abraham Lake

Abraham Lake

Alberta, Canada
This frozen lake looks like it's filled with gorgeous sculptures, but there's a more nefarious explanation behind its beauty. Those bubble-like forms underneath the surface are actually frozen pockets of methane released by dead vegetation on the man-made reservoir's bottom. It's become a popular destination for nature photographers over the years — but no one is likely to light a match near it.

Belhaven Bridge

Belhaven Bridge

Scotland
This apparent bridge-to-nowhere is certainly mystifying at first glance, but there's actually a perfectly natural explanation for why it looks this way: the tide. When the tide is low, the entirety of the structure is revealed. Locals use this bridge to walk over the water and get to the Belhaven Bay beach — a view that can be partially seen here


Fairy Glen Circle

Fairy Glen Circle

Isle of Skye, Scotland
Yes, it looks like something out of a "Lord of the Rings" movie or a fairy tale — in short, the Fairy Glen landscape itself is nothing short of mystical. Note, however, that the rock circles like the one in this photo are created by tourists — a practice that locals are against  — and usually removed after the throngs have gone home.

Fly Geyser

Gerlach, Nevada
This American Southwest geyser certainly looks natural, and it is, in part, but it might surprise you to know human error played a part in its formation. Two misguided drilling incidents — once more than 100 years ago in an effort to make the site usable for agriculture, and again in the 1960s by an energy company — uncovered geothermal activity at this site that has grown into extraordinary multi-colored mineral deposits.

To-Sua Ocean Trench

To-Sua Ocean Trench

Samoa
Located on Samoa's Upolu Island, this 30-meter deep dot of ocean is surrounded by tropical landscaped gardens and includes a ladder and platform that visitors can use to take a dip or sun themselves. Fed through a cave that leads to the ocean, To-Sua translates as "giant swimming hole."

Q’eswachaka Inca Bridge

Q’eswachaka, Peru
This rope bridge — the only remaining example of the Inca's handwoven bridge techniques — is 118 feet long and 6 stories above the river. It might look precarious, but it's actually rebuilt each year by members of four local communities.

Stonehenge

Wiltshire, England
This ancient megalithic site has been mystifying archaeologists and others for some time, in no small part because its massive stones have been traced to two quarries hundreds of miles away. It's theorized that people from the Neolithic era began building the site some 3,000 years ago.

Sarcofagi of Carajía

Carajía, Peru
Located 700 feet above the valley floor, these 15th century structures are a remnant of the Chachapoya people, who were eventually conquered by the Incas. At more than 8 feet tall, each was actually a burial site made of clay and reeds, and human skulls are still perched atop some.

Gippsland Lakes

Raymond Island, Australia
Algae blooms known as Noctiluca scintillans are characterized by their bioluminescent glow at night, and this species flourished in this area of Australia after a series of bushfires and weather events that dumped ash and nitrogen-laden organic matter into the lake in 2006 and 2007. The bioluminescence has since faded, but still exists.

Tigray Region, Ethiopia
This church in the sky is mystifying in and of itself, but even more so when you consider that worshippers have to scale a more than 600-foot rock face to get to it.

Ik Kil Cenote

Ik Kil Cenote

Yucatan, Mexico
This lush underground swimming hole, near the Mayan Chichen Itza ruins, was likely formed after a collapse of limestone formations. It's a public swimming hole today — with a carved staircase leading down into it — but was once used by the Mayans as a human sacrificial site.

Puzzlewood

Coleford, England
It's been suggested that this ancient forest inspired J.R.R. Tolkien's "The Lord of the Rings," and it's certainly easy to see why. Used for ore mining in Roman times, visitors today will find not only a wild, moss-covered landscape, but the same trails and footbridges used in earlier times.

Jigokudani Monkey Park

Jigokudani Monkey Park

Yamanouchi, Japan
Wild macaques, also known as snow monkeys, descend from higher elevations in winter to sit in this park's hot springs during the day, and go back into the forest at night. The only monkeys in the world known to engage in such behavior, website Snow Monkey Resorts notes that the animals learned the practice from watching humans do it.

Tunnel of Love

Ukraine
Around 2 to 3 miles in length, this section of industrial railway and its covered arches has been taken over by forest growth. Frequented by couples and others who find its lush foliage enchanting, it's also still used by trains that carry wood to a nearby fiberboard factory.
