This campground features 44 first-come, first-served campsites, each equipped with picnic tables and fire grates, with pit toilets available on-site.

Rock climbers, stargazers, and nature lovers flock to this site for its dramatic high-desert landscape and exceptionally dark skies. The area is also close to other Joshua Tree National Park highlights such as Barker Dam, Skull Rock, and Keys View. Note that no water is available on-site, so visitors should arrive fully stocked. The campground is highly sought-after during weekends, so early arrival is recommended. With its rugged beauty, outstanding trail access, and proximity to some of Southern California's most stunning desert scenery, Hidden Valley is a premier destination for RV and tent campers alike.
