25 Earth Locations That Look Like Another Planet
You don’t need a rocket ship to visit another world. Right here on Earth, scattered across every continent, lie landscapes so bizarre, so visually staggering, that they seem to belong to a different solar system entirely. From blood-red waterfalls flowing over Antarctic ice to underground caverns that glow like a star field, our planet harbors secrets that rival anything science fiction has imagined.
These aren’t just pretty spots for Instagram. Many of these places exist because of extreme geological forces — volcanic fury, chemical reactions, millions of years of erosion — that have produced environments so strange, scientists actually use them as stand-ins for studying life on Mars, Europa, and beyond. NASA researchers have walked the crusts of acidic lakes in Ethiopia. Astrobiologists have drilled into Antarctic glaciers looking for clues about alien oceans. The alien is already here.
Whether you’re a seasoned explorer or an armchair traveler, this list of 25 Earth locations that look like another planet will leave you questioning everything you thought you knew about the world beneath your feet. Buckle up.
The Martian Deserts and Red Canyons
Mars is closer than you think — at least visually. These five locations on Earth share the Red Planet’s hallmark traits: rust-colored rock, bone-dry air, and a haunting, desolate beauty that makes you feel like the last person alive in the universe.
1. Wadi Rum, Jordan: The Valley of the Moon
Wadi Rum is so convincingly Martian that Hollywood has filmed it as the Red Planet multiple times — in The Martian, Rogue One, and Prometheus, among others. Its towering sandstone and granite cliffs rise up to 800 meters from the desert floor, streaked in shades of red and orange by iron oxide deposits. Wind-sculpted arches and narrow canyons cut through the rock in patterns that seem engineered by something other than nature. The silence here is total. Standing in Wadi Rum feels less like being on Earth and more like being marooned somewhere between here and infinity.
2. Valle de la Luna, Atacama Desert, Chile
The Atacama Desert is the driest non-polar desert on Earth, and its Valley of the Moon — Valle de la Luna — is its most otherworldly corner. Salt formations, clay ridges, and windblasted sand dunes create a landscape that has barely changed in millennia. Annual rainfall here averages less than 1 millimeter. NASA has used the Atacama to test Mars rovers and search for microbial life because the conditions so closely mirror Martian soil chemistry. Walking through it at dusk, when the formations turn purple and gold, you’d swear the sun setting is the wrong color for Earth.
3. Danakil Depression, Ethiopia: Earth’s Most Alien Place
At 125 meters below sea level and regularly hitting 50°C (122°F), the Danakil Depression is not just alien-looking — it’s actively hostile to human life. Hydrothermal vents push acidic brine to the surface, creating pools of neon yellow, green, and orange around volcanic craters. The Erta Ale shield volcano sits at its center, maintaining one of the world’s few permanent lava lakes. Extremophile bacteria thrive in conditions that would kill most life forms, making Danakil a hotspot for astrobiology research. It looks less like Earth and more like early Venus — volcanic, toxic, and savagely beautiful.
4. White Sands National Park, New Mexico, USA
Most deserts are tan or red. White Sands is blinding white — a 710-square-kilometer ocean of gypsum dune fields that represents the largest of its kind on the planet. Unlike silica sand, gypsum stays cool even under the desert sun, and its pure white expanse stretches to the horizon with almost no color variation. The effect is disorienting in the best possible way. Standing in the middle of White Sands, with dunes rolling in every direction and nothing breaking the monochrome except a pale blue sky, you could easily be standing on a moon of Saturn.
5. Bisti/De-Na-Zin Wilderness, New Mexico, USA
Hidden in the badlands of northwestern New Mexico, the Bisti Wilderness is a gallery of geological nightmares — in the most magnificent sense. Centuries of erosion have carved hoodoos, alien-shaped rock pedestals, and petrified wood into formations that have no business existing on a planet with normal gravity. Some look like mushrooms, some like melting faces, others like the bones of something enormous. There are no trails, no facilities, and very few visitors. Arrive at dawn and you’ll have an entire alien world to yourself.
Icy Worlds and Frozen Frontiers
If Martian landscapes represent one end of the extraterrestrial spectrum, icy moons like Jupiter’s Europa and Saturn’s Enceladus define the other. These frozen environments on Earth give you a visceral sense of what a world of ice might actually feel and look like.
6. Vatnajökull Glacier, Iceland: Europe’s Largest Ice Cap
Vatnajökull covers roughly 8% of Iceland’s total landmass — about 7,900 square kilometers of ice reaching depths of nearly 1,000 meters. Its glacial caves shift and reform each year as melt water carves new passages through the ice. The interior of these caves glows in a blue so intense it seems artificial, filtered through centuries of compressed ice that has expelled all its air bubbles. Scientists studying Europa frequently reference glacier systems like Vatnajökull when modeling what might exist beneath that moon’s icy crust.
7. Mendenhall Ice Caves, Alaska, USA
Inside the Mendenhall Glacier near Juneau, a network of ice caves pulses with ethereal blue light. The glacier itself is receding — it has retreated more than 3 kilometers since 1958 — but while it lasts, the caves it exposes are extraordinary. Streams of meltwater carve tunnels through ice tens of thousands of years old, and standing inside one feels like being at the bottom of a frozen ocean. The walls glow, the ceiling drips, and the acoustics swallow sound whole.
8. Blood Falls, Antarctica
Taylor Glacier in Antarctica has a secret: a five-story outflow of deep red water that stains the white ice like an open wound. The color comes from iron-rich, hypersaline water that originates in an ancient subglacial lake, trapped beneath the glacier for over a million years. When the brine contacts oxygen, the iron oxidizes — the same chemistry that rusts metal — turning the water blood red. The microbes living in that dark, salty, oxygen-free lake have fascinated astrobiologists for decades. They’re the closest thing on Earth to what might inhabit the subsurface oceans of icy moons.
Aquatic Oddities and Submerged Realms
Water is the universal solvent, and in these four locations, it’s done something extraordinary — creating lakes, seas, and sinkholes that look pulled from the imagination of a science fiction author.
9. Lake Hillier, Australia: The Pink Lake
From above, Lake Hillier on Western Australia’s Middle Island looks like someone filled a lake with strawberry milkshake. Its vivid, bubblegum-pink color persists year-round and remains pink even when you bottle the water and take it home. Scientists attribute the color to a combination of algae — specifically Dunaliella salina — and halophilic bacteria called Salinibacter ruber that thrive in its extreme salinity. The lake sits separated from the Southern Ocean by only a thin strip of forest, creating a surreal triptych of pink, green, and blue that seems to belong to a world with very different physics.
10. Mono Lake, California, USA: Tufa Towers
Mono Lake is three times saltier than the ocean and 80 times more alkaline, and it’s been accumulating those minerals for roughly 760,000 years. The result: limestone tufa towers, formed by the interaction of calcium-rich freshwater springs with the carbonate-heavy lake water, rising like ancient spires from the surface. When water levels dropped in the 20th century due to Los Angeles diverting inflows, the tufa was exposed in all its alien glory. The lake and its ghostly formations were famously used as a stand-in for a distant planet in the original Planet of the Apes franchise.
11. The Great Blue Hole, Belize
Roughly 70 kilometers off the coast of Belize, a perfectly circular marine sinkhole drops 300 meters straight down into the Caribbean Sea. It spans over 300 meters in diameter and is so dark and deep it appears as a deep navy void in aerial photography. Jacques Cousteau rated it one of the world’s best dive sites in 1971. More recently, a 2018 expedition using submarines documented the interior — finding layers of ancient stalactites and stalagmites that confirmed it was once a dry cave system before sea levels rose. From above, it genuinely looks like a pupil staring back at the sky.
12. Salar de Uyuni, Bolivia: The World’s Largest Salt Flat
Bolivia’s Salar de Uyuni stretches across 10,582 square kilometers of the Altiplano — enough salt to cover the entire country of Jamaica three times over. During the dry season, its white crystalline surface, cracked into perfect hexagonal tiles, stretches to the horizon without a single visual anchor point. After the rains, a thin layer of water turns the entire flat into a flawless mirror, reflecting the sky so perfectly that the horizon disappears. You can’t tell where Earth ends and sky begins. It’s the closest thing to floating in space you can experience with both feet on solid ground.
Volcanic Vistas and Geothermal Wonders
Volcanoes have been reshaping Earth for 4.5 billion years, and in three remarkable locations, the results look less like anything you’d expect on this planet and more like dispatches from the surface of Io — Jupiter’s violently volcanic moon.
13. Fly Geyser, Nevada, USA
Fly Geyser isn’t entirely natural — it was accidentally created in 1964 during a geothermal energy exploration attempt. A well was drilled but never capped, and mineral-rich geothermal water has been continuously erupting ever since, building up a layered cone of calcium carbonate and other minerals that reaches roughly 1.5 meters tall. Thermophilic algae coat the formation in vivid streaks of red, green, and orange. Water spouts from three separate vents simultaneously. It looks like something alive — a coral reef crossed with a volcanic vent — and utterly unlike anything else in the American West.
14. Grand Prismatic Spring, Yellowstone National Park, USA
The Grand Prismatic Spring is the largest hot spring in the United States and the third largest in the world, measuring roughly 90 meters in diameter and dropping to depths of about 50 meters. Its concentric rings of color — deep blue at the center (too hot for life), transitioning through green, yellow, and orange toward the cooler edges — are produced by communities of thermophilic bacteria called cyanobacteria, each adapted to a specific temperature band. From above, it looks exactly like an alien eye staring up from the surface of some hot, strange world. The steam rising from it doesn’t help dispel that illusion.
15. Darvaza Gas Crater, Turkmenistan: The Door to Hell
In the middle of the Karakum Desert, a crater roughly 70 meters wide and 30 meters deep has been burning continuously since 1971, when Soviet geologists accidentally drilled into a natural gas pocket. They lit it on fire expecting the gas to burn off in days. It has not stopped burning in over 50 years. At night, the orange glow of the Darvaza crater — nicknamed “the Door to Hell” — illuminates the surrounding desert for kilometers. It is the most accurate representation of what the surface of a volcanically active exoplanet might look like, available without a rocket.
Mystical Forests and Eerie Ecosystems
Some places look alien not because of geology, but because the life forms that have evolved there are so strange, so perfectly adapted to isolation, that they’ve become unrecognizable as Earth-life.
16. Socotra Island, Yemen: The Alien Island
Socotra has been isolated from the African continent for somewhere between 6 and 7 million years, and in that time, its flora has evolved into something that looks designed by a committee that had never seen a normal tree. The Dragon’s Blood Tree (Dracaena cinnabari) grows in a perfect umbrella shape — branches spreading laterally like an inside-out tree, holding a dense canopy above a sparse, desert-adapted trunk. They cover hillsides in formations that look like a forest painted by someone who’d only ever heard about forests. About 37% of Socotra’s 825 plant species exist nowhere else on Earth.
17. Waitomo Glowworm Caves, New Zealand
Deep in the limestone country of New Zealand’s Waikato region, the ceilings of the Waitomo cave system are carpeted with thousands of Arachnocampa luminosa — a species of glowworm found only in New Zealand. Each larva produces a bioluminescent light and hangs silken threads to trap prey. The effect when you drift beneath them on a small boat in total darkness is of a night sky so clear and dense with stars it seems impossible. It’s one of the few places on Earth where you can genuinely feel like you’re traveling through deep space while sitting in a rowboat.
18. Lençóis Maranhenses National Park, Brazil
For most of the year, Lençóis Maranhenses looks like a coastal desert: vast white sand dunes rolling inland from the Atlantic coast of northeastern Brazil. But from January to June, seasonal rains fill the valleys between the dunes with crystal-clear freshwater lagoons that glow turquoise and green against the white sand. The lagoons support fish populations that arrive each year via floodwater — a fact that still puzzles biologists about how they survive the dry season at all. The combination of white dunes and vivid blue lagoons creates a landscape that seems far too surreal to have formed by normal atmospheric precipitation.
Geological Giants and Unearthly Formations
The final group spans everything from hexagonal volcanic columns to floating mountains, razor-sharp limestone forests, and swirling multicolored rock. These are the places that make geologists’ hearts race — and everyone else’s brain short-circuit.
19. Giant’s Causeway, Northern Ireland
About 60 million years ago, a volcanic eruption cooled slowly enough to allow the basaltic lava to contract and crack in a remarkably uniform pattern — producing roughly 40,000 interlocking hexagonal columns that descend from cliffs into the sea. The regularity of the columns is striking enough that ancient myths attributed them to a giant named Finn McCool who built a road to Scotland. Walking across the Giant’s Causeway, the geometric perfection underfoot feels computational, almost mechanical. It’s the kind of formation that would make any planetary geologist’s day if found on another world.
20. Tianzi Mountains, China: The Avatar Peaks
The Tianzi Mountains in Hunan Province consist of towering quartzite sandstone pillars, some rising over 1,000 meters, draped in subtropical vegetation and frequently swathed in cloud. They inspired the floating Hallelujah Mountains of Pandora in James Cameron’s Avatar — and unlike the film’s digital creations, these are real, navigable by a network of mountain paths and cable cars. The peaks formed as weaker surrounding rock eroded away over 380 million years, leaving these spectacular columns behind.
21. Tsingy de Bemaraha, Madagascar
“Tsingy” means “where one cannot walk barefoot” in Malagasy, which gives you an accurate sense of what this place is like. Tsingy de Bemaraha National Park protects a vast forest of razor-sharp limestone needles — some reaching 90 meters high — formed by millennia of rainfall dissolving the rock from the top down. Moving through the tsingy requires a harness and a high pain threshold. It’s a landscape that feels designed to be impenetrable, like a natural fortress on a planet that evolved to protect itself.
22. The Wave, Arizona, USA
The Wave in the Vermilion Cliffs wilderness of northern Arizona is a formation of Navajo Sandstone — layers of ancient sand dunes compressed and cemented over 190 million years — then sculpted by erosion into flowing, concentric curves of red, orange, and cream. The patterns in the rock swirl like something in motion, frozen at the moment of flow. Entry is strictly limited to 64 people per day by permit lottery, partly to protect the fragile formation. Up close, its curves look less like rock and more like the surface of something biological.
23. Goblin Valley State Park, Utah, USA
Goblin Valley contains thousands of sandstone hoodoos — called “goblins” — ranging from a few feet to several stories tall. They take the form of rounded, mushroom-capped pedestals and oddly humanoid shapes because the rock erodes at different rates depending on hardness. Walking through the valley feels like wandering through a crowd that has been turned to stone mid-movement. The landscape inspired a scene in the 1999 film Galaxy Quest, cast as an alien planet, and it’s not hard to see why.
24. Zhangye Danxia Landform Geological Park, China: The Rainbow Mountains
The Rainbow Mountains of Gansu Province display bands of color — vivid crimson, gold, green, and even blue — stacked in horizontal layers across their faces. These colors formed over 24 million years as red sandstone and other mineral-rich deposits accumulated, then were compressed, uplifted, and exposed by erosion. The effect is a mountain range that looks painted. The colors intensify dramatically in wet conditions and at golden hour, when the saturation seems to exceed anything a camera can properly capture. China designated the site a UNESCO World Heritage area in 2010.
25. Factory Butte, Utah, USA
Factory Butte is less famous than its Utah neighbors — Goblin Valley, Arches, Bryce Canyon — but arguably more unsettling. It’s a flat-topped mesa of gray shale and mudstone rising from the Henry Mountains badlands, surrounded by an expanse of pale, barren earth with almost no vegetation. The complete absence of color, the flat-topped geometry, and the isolation create the impression of a structure dropped into a wasteland by something that wasn’t building for human aesthetics. It looks like a outpost on a barren moon — functional, severe, and utterly indifferent to the presence of visitors.
Our Planet’s Limitless Strangeness
These 25 locations barely scratch the surface of Earth’s capacity for self-reinvention. Our planet has been experimenting for 4.5 billion years — folding, burning, freezing, dissolving, growing, and rebuilding — and the results, as you’ve seen, are extraordinary.
What’s remarkable is that many of these places also serve real scientific purpose. They help us understand what other worlds might look like, what life might survive in extreme conditions, and what processes may have shaped planets we’ve never visited. The alien is already here, and it’s been here all along.
If content like this makes you want to explore the world’s strangest corners from your couch first, sites like List25 are built exactly for that — delivering the kind of fascinating, fact-driven deep dives that make you genuinely smarter about the planet you’re living on.
Protect these places when you can. Travel to them when you’re able. And the next time someone tells you there’s nothing left to discover on Earth, send them this list.

Frequently Asked Questions
Which Earth location looks the most like Mars?
Wadi Rum in Jordan is the most widely recognized Earth location for its Mars-like appearance. Its red sand, iron-stained sandstone cliffs, and desolate silence have made it Hollywood’s go-to stand-in for the Red Planet. The Atacama Desert’s Valle de la Luna is another strong contender, and NASA has actually used the Atacama for Mars rover testing due to its similar soil chemistry.
Are any of these locations used by NASA or scientists for research?
Yes, several are active research sites. The Danakil Depression in Ethiopia is studied for its extremophile organisms, which help scientists understand how life might survive on other planets. Blood Falls in Antarctica has been a major focus for astrobiologists studying potential life in subsurface oceans on moons like Europa. The Atacama Desert has hosted Mars rover testing programs.
Can tourists visit all 25 of these locations?
Most are accessible to tourists with appropriate planning, but some have restrictions. The Wave in Arizona requires a permit obtained through a competitive lottery (only 64 people per day are allowed). Fly Geyser in Nevada was previously on private land but now requires a permit through the Bureau of Land Management. The Danakil Depression requires a licensed guide due to safety and political considerations. Wadi Rum is widely visited but check current travel advisories for Jordan.
Why do these places look so alien?
Each has a different explanation, but common factors include extreme mineral deposits (producing unusual colors), volcanic or geothermal activity (creating bizarre formations and toxic environments), extreme aridity or cold (preventing vegetation and preserving strange landforms), and millions of years of erosion acting on unusual rock types. In some cases, unique biological organisms — bacteria, algae, bioluminescent creatures — produce colors and effects that simply don’t exist in everyday environments.
Which location is the hardest to visit?
Tsingy de Bemaraha in Madagascar is arguably the most physically demanding — traversing the razor-sharp limestone requires specialized equipment and a high fitness level. Blood Falls in Antarctica requires an expedition trip to one of the most remote continents on Earth. The Bisti/De-Na-Zin Wilderness in New Mexico is less extreme to reach but has no trails or services, requiring solid navigation skills.
Are these landscapes at risk from climate change?
Several are directly threatened. The Mendenhall Glacier in Alaska has retreated more than 3 kilometers since 1958 and continues shrinking. Vatnajökull in Iceland is losing mass annually. The glowworm caves in New Zealand face risks from tourism-related humidity changes. Even salt flats like Salar de Uyuni are under pressure from lithium mining operations in the region. Many of these places may look different — or disappear entirely — within a century.
