Joshua Tree National Park is an American national park in southeastern California, east of San Bernardino and Los Angeles and north Palm Springs. It is named after the Joshua trees (Yucca brevifolia) native to the Mojave Desert.
The park includes parts of two deserts, each an ecosystem whose characteristics are determined primarily by elevation: the higher Mojave Desert and the lower Colorado Desert. The Little San Bernardino Mountains traverse the southwest edge of the park.
The majority of the 500 campsites in the park are available by reservation. Reservations can be made the same day or up to 6 months in advance and can be booked on recreation.gov. First-come, first-serve campsites are highly competitive on holidays, most weekends, and the springtime. Sleeping in your vehicle overnight along the roadside or at a roadside pull off is not allowed.
