America’s biggest desert is cold, dry, and hiding across 190,000 square miles of Nevada

America’s biggest desert isn’t hot

Most people hear “desert” and think scorching sand. But the Great Basin flips that on its head.

This is a cold desert, the largest in the United States, stretching about 190,000 square miles across Nevada and into neighboring states.

Snowy winters give way to hot, dry summers, and wide valleys sit between mountain ranges that run north to south like ribs. The Sierra Nevada blocks Pacific moisture, leaving just 6 to 12 inches of rain a year.

What fills the space between those ranges is worth the long drive.

No river here ever reaches the ocean

Every drop of rain that falls in the Great Basin stays in the Great Basin. Water either evaporates or sinks underground.

Thousands of years ago, melting glacial ice filled these valleys with massive lakes. Now, only salt flats, dry lake beds called playas, and seasonal wetlands remain.

Mountain peaks top 9,000 feet while valley floors sit above 4,000.

The Western Shoshone, Paiute and Ute have called this land home for at least 10,000 years, long before anyone gave it a name on a map.

A 287-mile stretch with almost nothing on it

US Highway 50 cuts across central Nevada, and in 1986, Life magazine called it “The Loneliest Road in America.”

The reporter said there were no attractions along the 287-mile stretch and recommended survival skills to drive it. Nevadans took that as a compliment.

The route passes through Austin, Eureka and Ely, small towns with deep roots in the state’s mining past. Long straightaways open up to sagebrush valleys and distant peaks that seem to go on forever.

Carvings in volcanic rock from 10,000 years ago

About 24 miles east of Austin, at roughly 6,500 feet, Hickison Petroglyph Recreation Area sits right off US 50. Western Shoshone people carved these images into volcanic tuff an estimated 10,000 years ago.

A half-mile interpretive trail winds through the rock outcroppings where you can see patterns of lines, circles and shapes. Nobody knows exactly what they mean.

The Bureau of Land Management keeps the site free to visit, and you can picnic or camp there overnight.

Lehman Caves stays 50 degrees all year long

At the base of Wheeler Peak, Lehman Caves stretches about two miles underground, making it the longest known cave in Nevada.

More than 300 rare shield formations line the walls and ceilings, far more than most cave systems anywhere. President Warren G. Harding first protected the caves as a national monument in 1922.

Right now, a lighting replacement project limits tours to 30-minute Gothic Palace Lantern Tours. The temperature holds steady at 50 degrees Fahrenheit, so bring a jacket even in July.

Bristlecone pines that sprouted before the pyramids went up

Great Basin National Park grows some of the oldest known non-clonal living organisms on Earth. The park’s famous Prometheus tree was estimated to be about 4,900 years old before someone cut it down in 1964.

You can reach the most accessible grove on the Bristlecone Pine Trail, a 2.8-mile round trip from the trailhead near Wheeler Peak Campground.

These trees survive in harsh, windswept ground where almost nothing else grows. Above the groves, the 13,063-foot Wheeler Peak holds Nevada’s only remaining glacier.

Walk through slot canyons carved from soft clay

Cathedral Gorge State Park sits near Panaca in eastern Nevada and became one of the state’s first four state parks in 1935.

Erosion cut dramatic spires and narrow slot canyons from soft bentonite clay across a long, narrow valley. You can step through cave-like openings and follow winding passages between the formations.

The Civilian Conservation Corps built picnic shelters and stone fire pits here in the 1930s, and they still stand today. Miller Point, near the park entrance, gives you a full view of the entire canyon.

Mustangs graze across 15.6 million acres of open range

Nevada has more wild horses than any other state. The Bureau of Land Management manages 83 herd management areas across roughly 15.6 million acres, and you may spot mustangs grazing in valleys or crossing open sagebrush flats from any backroad in the state.

They share the range with pronghorn antelope, mule deer, coyotes and golden eagles. In 1971, Congress declared wild horses “living symbols of the historic and pioneer spirit of the West.”

Seeing them silhouetted against a basin-and-range backdrop puts that phrase into focus.

Rocking chairs still sit inside Berlin’s abandoned buildings

Berlin, at Berlin-Ichthyosaur State Park in central Nye County, emptied out around 1911 to 1914 and never came back.

Original buildings still hold rocking chairs, bottles and other artifacts from daily life over a century ago.

The same park holds the largest known concentration of ichthyosaur fossils, ancient marine reptiles that swam a warm ocean here about 225 million years ago.

Near Beatty, Rhyolite’s stone ruins include a three-story bank building. Next door, the Goldwell Open Air Museum fills the desert floor with large-scale outdoor sculptures.

98 miles of empty road near restricted military land

Nevada State Route 375 became the Extraterrestrial Highway in 1996, thanks to its location near the Nevada Test and Training Range and other restricted military lands.

The road runs about 98 miles between Warm Springs and Crystal Springs through some of the emptiest country in the Lower 48.

Rachel, the only community along the route, has a tiny population and a roadside stop that draws travelers for photos. Beyond the name, wide basins, distant mountain ranges and huge open skies fill every direction.

No gas stations line the route, so fill your tank before you go.

Red sandstone dunes from 150 million years ago

Valley of Fire State Park sits about 55 miles northeast of Las Vegas in the Mojave Desert.

Nevada’s oldest state park covers 40,000 acres of red Aztec sandstone formed from ancient sand dunes more than 150 million years ago.

You can find 2,000-year-old petroglyphs in excellent condition here, along with petrified trees.

Petroglyph Canyon to Mouse’s Tank is a popular trail, but Fire Wave and White Domes close every year from May 15 through Sept. 30. Red, orange and pink rock against blue sky fills every frame you shoot.

Six 30-foot stone kilns built for silver smelters in 1876

Ward Charcoal Ovens State Historic Park sits about 18 miles south of Ely and preserves six massive beehive-shaped stone kilns built in 1876.

Workers used them to make charcoal for silver smelters during Nevada’s mining boom. Each oven stands about 30 feet tall, built from local stone, and all six hold up well after nearly 150 years.

The park sits in a pinyon-juniper forest at about 7,000 feet, so temperatures run cool and the night skies go dark. Local legend says stagecoach bandits later hid inside the ovens from the law.

Explore Great Basin National Park in Nevada

You can find Great Basin National Park in eastern Nevada near the Utah border, about 295 miles north of Las Vegas and 234 miles southwest of Salt Lake City. The park spans 77,180 acres and costs nothing to enter.

Lehman Caves tours need tickets, but 2026 availability is limited during the lighting project. Wheeler Peak Scenic Drive climbs 12 miles and gains about 4,000 feet through several ecological zones.

The park holds International Dark Sky Park status, so plan a night for stargazing.
