Salar De Uyuni

Located in Bolivia, the Salar De Uyuni is the largest salt pan in the world. And when a thin film of water gathers on the surface it is also the world’s largest natural mirror.

How It Formed

Salar De Uyuni is the remains of a prehistoric lake that dried up and left behind void space of bright-white salt, rock formations, and cacti-islands.

The best time to visit is during the months of July and October

Lake Natron

Lake Natron is located in Tanzania and it is known as one of the scariest lakes in the world because it turns birds and animals into stone.

What It Is

Lake Naton is a high salt and high alkaline lake. The alkalinity of the lake can reach a pH level of greater than 12. When animals come into contact with the water, calcium starts to accumulate in their body tissue—which is called calcification—essentially turning them into stone.

Die Rakotzbrück

The Rakotzbrücke, also known as the Devil’s Bridge, is one of Germany’s most enchanting oddities. Built in the 19th century, it’s celebrated for its eerie precision—the way its arch reflects in the still water below creates a flawless, otherworldly circle that feels almost too perfect to be real.

Restricted Access

While the bridge is still very popular with tourists, no one is actually allowed to walk on it. Even so, its fairy tale look draws in tons of visitors each year.

Extreme Winds

These trees look like nature’s own sculptures—permanently bent and twisted by relentless Antarctic winds. The area ranks among the windiest spots on Earth, and the trees’ dramatic shapes stand as living proof of just how powerful those gusts can be.

Deadvlei

Located in Namibia, the name Deadvlei means “dead marsh”, and it is a forest of sun-blackened unalive trees that sit in a white clay pan which is basically a dried oasis.

A Desert Oasis

The lack of water in the extreme heat forces the roots of trees to come outside looking for moisture. Not only is the area surrounded by rust-orange giant sand dunes, but they’re also the highest sand dunes in the world.

A Scuba Diver’s Dream

During the winter, everything is normal and the lake is surrounded by a county park. But the park is also surrounded by mountains, so in the spring, the valley below fills with clear blue water sending the entire park deep underwater—making it a popular scuba diving spot.

Eternal Flame Falls

One of nature’s coolest party tricks, Eternal Flame Falls in New York hides a flickering secret. Behind its gentle cascade burns a small, steady flame—fueled by natural gas seeping from the rocks—that glows year-round, even as water rushes right over it.

What Causes the Flame

The flame is fueled by natural gases that emit from the base of the waterfall. The flame can sometimes be extinguished, but can be relit. It will continue to burn for very long periods of time.

How It Grew

How It Got There

Crafted by artist Guido Galletti, the Christ of the Abyss statue rests beneath the waves of the Mediterranean Sea. It was placed there in 1954 to honor Dario Gonzatti, the first Italian to use scuba gear. Standing 17 meters underwater, the bronze figure of Jesus with outstretched arms still watches serenely over the deep to this day.

What Makes It Colorful

The waters change colors by the presence of different types of algae and minerals. The water temperatures and sunlight activate vibrancy levels, so on a good day the water is extra colorful.

Jellyfish Lake

Jellyfish Lake in Palau is one of the South Pacific’s most surreal destinations. Here, visitors can literally dive into a dreamlike world—swimming among millions of harmless golden jellyfish that drift gracefully through the water like living lanterns.

Millions of Jellyfish

In 2005, there were an estimated 30 million jellyfish living in the lake. The majority of the jellyfish in the lake do not sting, as there are no natural predators in the lake so they have lost their ability to sting.

Blood Falls

In the Antarctica, among stark white snowy mountains is a small waterfall that pours out deep-red water, making it a creepy natural phenomenon.

What Makes It Red

The red coloring is due to oxidized iron in brine saltwater, the same process that gives the iron a dark red color when it rusts.

The Painted Hills are located in Oregon, and they are best known for their natural painted design that shows up in vibrant yellows, reds, golds, and blacks.

What Makes Them Colorful

Minerals embedded in the rock give these hills their mesmerizing rainbow tones. As sunlight and moisture shift throughout the day, the colors seem to change right before your eyes—creating a landscape that never looks quite the same twice.
