Joshua Tree National Park boasts unusual desert plants and flowers.

Extensive stands of Joshua trees and a colorful palette of plants and animals exist in this beautiful desert region of east central California.

About 80 percent of the park, which covers 794,000 acres, is designated wilderness.

Two deserts come together here. The lower, drier Colorado Desert occupies the eastern half and the higher, slightly cooler and wetter Mojave Desert, the habitat of the namesake Joshua tree, occupies the western half. Within the park are five palm oases.

Thirty-five miles of the California Riding and Hiking Trail pass through Joshua Tree. Several hiking trails, extending three to four miles, lead to canyons and excellent views of mountains and valleys.

The eight-mile Boy Scout trail follows the western edge of the Wonderland of Rocks. Short nature trails with informational signs lead to rock formations, scenic overlooks and an oasis.

Six backcountry dirt roads, ranging from two to 23 miles, are open to mountain bikes and four-wheel-drive vehicles. Bikes are not allowed on trails.

Hikers must carry their own water and firewood. Water is available at the Oasis Visitor Center, other centers, a ranger station and two campgrounds.

A permit is required for backcountry camping.
