Located in Antarctica’s McMurdo’s Dry Valleys, the shallow Don Juan Pond is the world’s saltiest body of water. With a salt content that puts the Dead Sea to shame, it remains liquid even at -58 degrees Celsius (-50 Fahrenheit).

At four inches deep, Don Juan Pond looks more like a large puddle than an actual pond, but it has fascinated scientists for decades. A liquid puddle of this size in an alien-like environment where temperatures can drop to -50 degrees Fahrenheit was bound to draw attention at one point, and the tiny body of water has been buzzing with scientists since it was discovered in 1961. A quick analysis revealed its salt content to be around 40%; to put that into perspective the world’s oceans have a salinity of 3.5%, the Great Salt Lake varies between 5 and 27 percent, and the famous Dead Sea is 34% salt.

Gaoqi Ling is a natural wonder in China’s Hunan Province, a mountain of perfectly smooth rock with an extremely narrow ridge that people love to traverse despite the apparent danger.

China’s Danxia Park is famous for its unique landforms, particularly the multicolored “Rainbow Mountain,” but it is home to other less-known but just as intriguing natural formations. Gaoqi Ling is one such natural wonder. Originally a watershed, this natural wonder had its steep ridges shaped by the water washing over them and then smoothed out by rain and wind. Today, the sharp ridges are often compared to a giant knife edge or the spine of a sleeping dragon with its ribs extending outwards.

Benten Mountain, in Tokushima Prefecture, is considered Japan’s shortest natural mountain with a height of just 6.1 meters and a diameter of under 60 meters.

Located in the middle of fertile paddy fields along Tokushima’s Prefectural Road 10, Benten Mountain is the shortest mountain in Japan and one of the shortest in the world. It takes the average person just one minute to reach the summit and yet over 10,000 people make the journey here every year for this specific purpose. For some, it’s just the novelty of scaling a 6.1-meter-tall mountain, others come to admire the wax tree, camelias, and other flowers that call the rocky mass their home, and a few make the short trek to reach the Itsukushima Shrine built in honor of Benzaiten, the goddess of wisdom.

The Island of Sark, the smallest of the Channel Islands located between France and England, is home to the world’s smallest prison still in use today – a tiny building with only two cells.

There are no cars, no roads and no streetlights on Sark Island, but there is a small prison dating back to the year 1856. Featuring just two tiny cells – one measuring 6 feet by 6 feet and the other 6 feet by 8 feet – separated by a narrow corridor, it holds the Guinness World Record for the ‘world’s smallest prison’. It’s only fitting that an island measuring just under 5 kilometers long and 1.6 kilometers wide, with a population of under 600 people, be home to the world’s smallest prison. The two cells only have small, wood-slatted beds with thin mattresses for inmates to sleep on, and inmates can only be held here for a maximum of two days, after which they have to be transferred to the larger prison facilities on the neighboring Guernsey Island.

China’s Guizhou Province is home to about a dozen conical hills known as the Anlong Pyramids because of their resemblance to the much more famous pyramids of Egypt.

In recent years, Anlong County has become a popular tourist destination thanks in no small part to its pyramid-like mountains which have captured the imaginations of millions of people around the world. Apart from their pyramid-like shape, these formations also feature layers of rock stacked on top of each other so neatly that you could swear they were placed like that by someone or something. Ever since photos and videos of the Anlong Pyramids started circulating online around 2018, conspiracy theories about their origin began appearing as well, and despite experts’ best efforts to convince the public that these pyramids are completely natural, some people still believe that they are the work of an ancient human civilization or of aliens.

The Recreo Verde tourist complex in Venecia de San Carlos, Costa Rica, is home to a tiny mountain cavern that has come to be known as The Cave of Death due to its ability to kill any creature that enters it.

Located on the edge of the Poas Volcano, la Cueva de la Muerte is only 2 meters deep and 3 meters long, which makes it a seemingly cozy refuge for insects, birds, and small animals looking for shelter. But appearances can be deceiving, as entering this tiny cavern results in an almost instant death. Although the tiny cave looks harmless to the naked eye, it is filled with carbon dioxide, a colorless, odorless, tasteless gas that also happens to be extremely toxic. To demonstrate just how lethal the Cave of Death actually is, local guides place a lit torch inside the cavern and it is extinguished instantly by the absence of oxygen and the high concentration of carbon dioxide.

Peñón de Vélez de la Gomera, a small rock in northern Africa conquered by Spain in 1564, holds the title for the world’s smallest national border, measuring just 85 meters in length.

Spain has almost 2000 kilometers of land borders with Portugal and France, but it also has much smaller borders with countries like Andorra, the United Kingdom (Gibraltar), and Morocco. It is with the latter, the African nation of Morocco, that Spain shares the smallest land border in the world, an 85-meter-long stretch of land linking a rock about 19,000 square meters in size to the Moroccan coast. Peñón de Vélez de la Gomera has been Spanish territory since 1564 when it was conquered by Admiral Pedro de Estopiñán, and although Morocco has repeatedly laid claim to it, Spain has never agreed to return the land and actually has troops stationed there to enforce Spanish rule.

Stretching for 65 miles (105 km) between the towns of Of and Bayburt in Eastern Turkey, the D915 is an extreme road regarded by many motorists as the most diffcult in the world.

For many years, Bolivia’s Yungas Road, aka the “Death Road”, held the unofficial title of world’s most dangerous road. Photos and videos of motorists navigating the gravel track winding its way through the Cordillera Oriental mountain range to an altitude of 4650 meters have made Yungas one of Bolivia’s most popular tourist attractions, drawing around 25,000 people every year. However, according to some adventurers, there is one less popular road that surpasses the Death Road in terms of difficulty. Linking Turkey’s Northeast Anatolia Province to the Black Sea, the D915 mountain road features a myriad turns and dangerous drop-offs that make it extremely perilous to traverse even for the most skilled drivers.

The Santuario Della Beata Vergine Maria Delle Grazie, in Italy’s Lombardia region, is an old church famous for having a real taxidermied crocodile hanging from the ceiling.

What’s the last thing you expect to see when you look up in a church? Granted, there are plenty of interesting answers one can think of, but ‘a crocodile’ definitely ranks up there with the quirkiest of them. But if you travel to the small municipality of Curtatone, in Lombardia, Italy, you’ll find a church with a five-century-old crocodile hanging from the ceiling. It’s a peculiar sight, to say the least, but one that has been around for as long as anyone can remember. How the croc wound up at the Santuario Della Beata Vergine Maria Delle Grazie is, and will probably remain a mystery, but its purpose had been linked to religious symbolism.

Mori Ouchi, a cozy cafe in Tokyo’s laidback Shimokitazawa district, is famous for only catering to pessimists and people with a generally negative mindset.

Negative people tend to get a bad rep and are constantly told to be more positive, but, if you think about it, is there really anything wrong with being negative? The founder of Mori Ouchi, a small cafe in Shimokitazawa, Tokyo, certainly doesn’t think so. A self-described gloomy person, he got the idea for like-minded people over a decade ago but only decided to open it three years ago, during the COVID-19 pandemic. The man had always felt like negative people were more sensitive and more easily hurt than others, so he created a space dedicated exclusively to them.

Inishmore, the largest of Ireland’s Aran Islands, is home to a remarkable natural wonder, a rectangular pool cut so straight into limestone that it looks man-made.

Also known as “The Wormhole” or “The Serpent’s Lair”, Poll na bPéist is a natural water basin with an edge length of approx. 10 by 25 meters within a stone formation. It can only be accessed by walking along the cliffs south of the ancient site Dún Aonghasa, but in recent years it has become famous for hosting the renowned Red Bull Cliff Diving World Series. The most fascinating thing about Poll na bPéist is its remarkable rectangular shape, which has led many to question its natural origins and sparked several theories, including that it is the work of an ancient civilization.

A road leading to Bali’s Pandawa Beach that seems to split an entire plateau in half has sparked a heated online debate about the practicality of the project and its effect on local wildlife.

Featuring fine white sand and crystal-clear water, the picture-perfect beach of Pandawa was already one of Bali’s most beautiful seaside destinations, but the road dug into the limestone cliffs separating the beach from the rest of the island really catapulted it into the top tourist destinations on the island. Until only a decade ago, Pandawa Beach was only popular among locals, as the limestone cliffs secluded from foreigners’ eyes were notoriously hard to traverse. However, everything changed in 2012 when a road leading down to the beach was created by cutting through the cliffs. Today, that road has itself become somewhat of a tourist attraction in its own right, but also the topic of a heated debate.

His idea was a huge hit, and to this day thousands of people continue to enjoy subsidized ice cream at Coppelia Park, the world’s largest ice cream parlor.
