You probably picture a desert as a giant, sweltering sandbox with a few bored camels. Honestly, that's barely half the story. If we’re talking about actual desert locations in the world, we have to start by admitting that "desert" is a job description, not a temperature setting. A desert is just a place that loses more water through evaporation than it gets from rain or snow. That’s it. That is the whole biological secret. This definition is why the largest desert on Earth isn't the Sahara; it’s Antarctica. It’s a massive, frozen desert where the "rainfall" is basically non-existent, even if you’re standing on two miles of ice.
The Sahara is Not What You Think
People treat the Sahara like the gold standard for deserts. It’s huge, sure. It covers about 3.6 million square miles, which is roughly the size of the entire United States. But if you went there expecting 100% sand dunes, you’d be pretty disappointed. Most of the Sahara is actually hamada—which is just a fancy way of saying barren, rocky plateaus. It’s gravelly. It’s harsh. It’s mostly brown rocks and wind-swept stone.
The sand dunes, or ergs, only make up about 25% of the landscape.
Think about the Emi Koussi volcano in Chad. It’s the highest point in the Sahara, reaching over 11,000 feet. There are parts of the Sahara that actually get snow in the winter. It’s a land of extremes that defies the "Lion King" aesthetic we’ve been fed since childhood. Then you have the Nile River cutting through it like a literal lifeline. Without that specific geographic fluke, the history of human civilization would look completely different.
Why the Atacama is the Weirdest Place on Earth
If you want to talk about "dry," you have to talk about the Atacama in Chile. Some weather stations there have never, ever recorded a single drop of rain. Not in decades. Not in centuries. It’s the driest non-polar place on the planet.
NASA actually uses the Atacama to test Mars rovers. Why? Because the soil is so sterile and the environment is so intensely UV-blasted that it’s the closest thing we have to the Red Planet. But here’s the kicker: people live there. Thousands of them. They’ve adapted to harvesting water from the air using "fog nets." These are basically big mesh screens that catch the camanchaca (coastal fog) and drip it into pipes. It’s low-tech brilliance.
Unexpected Desert Locations in the World
Most travelers overlook the Gobi. Located between China and Mongolia, the Gobi is a "rain shadow" desert. The Himalayas are so tall that they literally block all the rain clouds from the Indian Ocean. By the time the air gets over the mountains, it’s bone dry.

The Gobi is freezing.
It’s a cold desert where you can see frost on the dunes. It’s also one of the most important paleontological sites ever. Roy Chapman Andrews, who some say was the real-life inspiration for Indiana Jones, found the first recognized fossilized dinosaur eggs here in the 1920s. He wasn't even looking for dinosaurs; he was looking for the origins of humanity. He failed at that, but he stumbled onto a "Flaming Cliffs" boneyard that changed science forever.
The Namib: Where the Ocean Hits the Sand
The Namib Desert in Namibia is probably the most photogenic place I’ve ever seen. It’s home to Sossusvlei, where you find these massive, bright orange sand dunes—some over 1,000 feet tall—contrasted against a deep blue sky. The sand is orange because it’s literally rusting. The iron oxide in the sand reacts with the air over millions of years.
Down in Deadvlei, there are skeletons of camel thorn trees that died 600 to 700 years ago. They haven't decomposed. The air is too dry for the bacteria that cause rot to even survive. They just sit there, scorched black by the sun, looking like a surrealist painting. It’s a graveyard that refuses to bury its dead.
The Mojave and the "Rain Shadow" Effect
Closer to home for many, the Mojave in the Southwest United States is a perfect example of how mountains dictate where deserts live. The Sierra Nevada mountains pull all the moisture out of the Pacific air. Death Valley, which is part of the Mojave, sits at 282 feet below sea level. It’s a heat trap. In 1913, it hit 134°F.
But go there in a "superbloom" year, and the whole place is covered in yellow wildflowers. It’s a dormant garden waiting for a single mistake by the clouds.
- The Sonoran: Different from the Mojave because it has two rainy seasons. This is why it’s the only place you’ll find the iconic Saguaro cactus.
- The Chihuahuan: Bigger than the Sonoran, mostly in Mexico, and higher in elevation, making it slightly cooler but incredibly biodiverse.
- The Great Basin: A "cold" desert that covers most of Nevada. It’s high, it’s dry, and it’s where you find the 5,000-year-old Bristlecone pines.
Moving Beyond the "Empty" Myth
We tend to think of desert locations in the world as "wastelands." That’s a dangerous word. It implies they are useless or empty. In reality, deserts are home to about 1 billion people. They are massive solar energy hubs. The Sahara alone could theoretically power the entire world if we could figure out the logistics of cleaning the sand off the panels and moving the electricity across oceans.
Biologically, they are survival labs. Take the Saharan silver ant. It can survive body temperatures of 128°F. It has evolved silver hairs that act like a space suit, reflecting sunlight. Or the Welwitschia plant in the Namib, which can live for 1,500 years by drinking nothing but morning dew.
Deserts aren't where life goes to die; they’re where life goes to prove how tough it is.
How to Actually Visit These Places Safely
If you’re planning to scout out these desert locations in the world, stop thinking about "survival" and start thinking about "preparation." Most people who get into trouble in the desert don't die of thirst—they die of heatstroke or, surprisingly, drowning. Flash floods in desert canyons are lethal because the parched ground can’t absorb a sudden downpour. The water just runs off like it’s hitting concrete.
- Water isn't for sipping. If you’re thirsty, you’re already dehydrated. Drink. Don't ration it until you're dizzy.
- Timing is everything. In the Danakil Depression (Ethiopia), the "cool" season is still over 90°F. Plan your window carefully.
- The Night Factor. Deserts lose heat instantly once the sun drops. The Sahara can swing from 100°F during the day to 30°F at night. Pack layers.
- Tires and Tech. If you’re driving in the Empty Quarter (Rub' al Khali) in Saudi Arabia, you need a satellite phone. Cell towers don't like sandstorms.
Actionable Insights for the Desert Traveler
If you want to experience these landscapes without becoming a cautionary tale, start with the "entry-level" deserts. The High Desert in Oregon or the Joshua Tree area in California offers the aesthetic and the environment with the safety net of nearby infrastructure.
For the more ambitious, look into the Wadi Rum in Jordan. You can stay in "Martian domes" and see the landscape where Lawrence of Arabia and The Martian were filmed. It’s accessible but feels like another planet.
Check the UNESCO World Heritage list for desert sites before you book. Places like the Air and Ténéré Natural Reserves in Niger are spectacular but require significant security and logistical planning. Always prioritize local guides who understand the "reading" of the dunes—wind patterns can erase a trail in minutes.
The most important thing to remember is that the desert doesn't care about you. It's not hostile; it’s indifferent. That indifference is what makes it beautiful, but it's also what makes it dangerous. Respect the humidity levels, watch the horizon for dust storms, and never underestimate how quickly a clear sky can turn into a wall of sand.
