▲This place is so distinct, it unsurprisingly was featured in a movie and a documentary: 'Journey Into Amazing Caves' (2001) and Discovery Channel's 'Planet Earth.'

▲Yellowstone National Park’s famed hot spring has a totally bizarre, colorful appearance, the result of pigmented bacteria and microbes that make their home in the warm mineral waters.

▲Salt formations, acidic hot springs, and gas geysers give this ghost town its alien-looking eeriness.

▲With average summer highs reportedly reaching up to 45°C (114°F), this hydrothermal area is among the hottest spots on Earth.

▲These miles and miles of jagged, rocky peaks sure are something, and that something doesn’t exactly scream “earthly.”

▲The landscape resembles a drowned desert or a sandy lake, depending on the perspective.

▲The valleys between the national park's rolling sand dunes fill up with water during the rainy season every year, giving this place its striking features.

▲These otherworldly-looking formations are the result of occasional sandstorms in the area.

▲This desert's most striking feature is its wind-shaped chalk rock formations that look like giant mushroom clouds frozen in time.

▲Craters of the Moon National Monument and Preserve owes its appearance to volcanic activity.

▲

Volcanoes don’t just exist on Earth. In fact, Jupiter’s moon Io is actually the most volcanically active location in our solar system.

▲

If planning a trip to the moon isn't in the books, consider the Moon Valley instead.

▲

There may not be goblins in this valley, but the whole park looks so different from most parts of the planet that it’s hard to imagine you’re still on Earth.

▲

This formation is the result of erosion of sandstone by water, hence its flowing shapes.

▲

The fact that it’s an International Dark Sky Park makes it look even more like another planet.
