What’s with the two deserts? Joshua Tree sits on a seam. The town and its national park straddle the line where two great deserts meet: the higher, cooler Mojave to the west — above about 3,000 feet, where the rain is a little more generous and the Joshua trees grow — and the lower, hotter Colorado Desert to the east, all creosote, ocotillo, and cholla cactus. Cross the park from one side to the other and the whole world changes: spiky Joshua-tree forests and piled boulders give way to open cactus flats and palm-shaded oases fed by water forced up along the San Andreas fault. Two deserts, one town at the gateway — which is a lot of strangeness for one stretch of California.
Then there are the rocks. Joshua Tree’s other signature is its boulders — great piles of pale monzogranite that formed underground about a hundred million years ago, rounded by water seeping along the joints and then laid bare by erosion. They stack into the Wonderland of Rocks, Skull Rock, Hidden Valley, and Jumbo Rocks, and they’ve made Joshua Tree one of the world’s great rock-climbing destinations, with thousands of routes scrambled, bouldered, and roped by climbers from everywhere. Even if you never rope up, the boulders are the desert’s natural architecture.
Why People Visit Joshua Tree
People come for the strangeness: trees out of a storybook, boulders made for scrambling, and a night sky so dark the Milky Way throws shadows. Pair the park with the town’s desert-arts scene and you have a high-desert getaway unlike anywhere else in California.
