From underwater rivers to glowing caves these are 25 places that look like they are from another planet.

Sea of Stars, Vaadhoo Island, Maldives
The surreal blue glow is caused by bioluminescent phytoplankton.
Turquoise Ice, Lake Baikal, Russia
In March, frost and sunlight create cracks in the frozen surface of this lake which cause these turquoise pieces of ice to protrude.
Glowworm Caves, Waitomo, New Zealand
About the size of mosquitos, these glowworms are only found in New Zealand.
Lake Hillier, Australia
The pink hue is due to algae and bacteria.
Caño Cristales River, Colombia
Due to a high level of biodiversity in and around the water, this river appears to flow in numerous colors.
Giant’s Causeway, Northern Ireland
Volcanic activity created these perfectly chiseled columns.
Underwater Waterfall, Mauritius Island
Created by ocean currents, sand is constantly being sucked down into the crevice.
Fingal’s cave, Scotland
Similar to Giant’s Causeway, these formations were once again created by volcanic activity.
Naica Mine, Mexico
The enormous crystals were formed by hydrothermal fluids rising from the heated Earth below.
Lake Natron, Tanzania
Another pinkish body of water, this time the hue is due to salt loving organisms that produce red pigment. Unlike Lake Hillier in Australia, the high salt content of this lake makes it inhospitable for numerous creatures.
Plitvice Lakes, Croatia
The oldest national park in southeast Europe is full of some of the most beautiful lakes, caves, and waterfalls on Earth.
Salar De Uyuni, Bolivia
This salt flat is so reflective that it is used to calibrate satellites.
Sentinels of the Arctic, Finland
This is what trees in Finland look like in winter
Skaftafell Ice Cave, Iceland
The tightly packed ice in these caves absorbs most of the light spectrum except for the color blue.
Bigar Waterfall, Romania
Locals refer to the place as “the miracle from the Minis gorge”.
Grand Prismatic Hot Spring, Wyoming
The colors in this hot spring are from pigmented microbes that grow near the edges.
Deadvlei, Namibia
Once a thriving forest, these trees are only a remnant standing against the encroaching dunes of the desert.
Socotra, Yemen
A third of the life on this isolated island is found nowhere else on the planet.
Yuanyang County, China
These terraced rice fields make for a stunning birds eye view.
Pamukkale Hot Springs, Turkey
Although these look like frozen terraces they are actually white limestone.
Fly Geyser, Nevada
After a well was drilled and left uncovered, algae bubbled up to create this extraterrestrial looking mound.
Aogashima, Japan
It’s a volcano inside a volcano.
Underwater River, Cenote Angelita, Mexico
The hydgrogen sulfate in this river sinks to the bottom and forms a river of its own.
Hidden Beach, Mexico
This hole was created by a military test explosion at some point during the 20th century.
Mount Roraima, South America
This tabletop mountain has been isolated for centuries and the landscape on top is similar to Socotra Island in its uniqueness.
