The Mojave is the smallest and driest of North America’s four major deserts, sprawling across about 47,000 square miles. Most of it is in southeastern California, with pieces reaching into Nevada, Arizona, and Utah. It’s the desert behind Las Vegas, Palm Springs, and Death Valley.
Where It Is
The Mojave sits between the Sierra Nevada on the west and the Sonoran Desert to the south and east. In California it covers the high desert around Lancaster, the stretch through the Antelope Valley, and the federal lands that include Death Valley and Mojave National Preserve.
What Makes It Different
The giveaway is the Joshua tree, which grows only here. The landscape is basin-and-range — parallel mountain ridges and flat valleys — and it’s high enough that winter nights get cold. The Colorado River and Lake Mead form the eastern edge.
Key Places Inside It
- Death Valley National Park — Badwater Basin, the lowest point in North America, plus salt flats and dunes.
- Mojave National Preserve — Kelso Dunes, the lava tube, and Joshua tree woodland.
- Joshua Tree National Park — the northwestern part sits in the Mojave; the rest drops into the Colorado Desert.
- Route 66 — cuts through the desert with stops like Elmer’s Bottle Tree Ranch and Roy’s Motel.
Climate and Timing
Summers run well over 100°F; winters can freeze. The comfortable windows are spring and fall, when wildflowers can bloom after a wet winter. Carry at least a gallon of water per person per day and tell someone your route — cell service is spotty.
Plants and Animals
Beyond Joshua trees, the desert has desert tortoise, bighorn sheep, and the Mojave ground squirrel, plus more than 200 bird species in wet years. It’s fragile: stay on roads and pack out what you bring in.
