Black Rock Campground lies among one of the thickest Joshua tree forests in Joshua Tree National Park. Its location on the park's northern perimeter makes it a popular rest stop for hikers, birders, horseback riders and RV campers. Black Rock is one of only two campgrounds in the national park that can be reserved during the busy winter season; it is open on a first-come, first-served basis from June 1 through September 30. Travelers who enjoy warm, dry winters flock to Joshua Tree from October through May, when temperatures hover between 70 to 90 degrees during the day and drop anywhere between 40 to 60 degrees at night. Summer is the park's off-season due to uncomfortably high desert heat. Black Rock is at an elevation of 4,000 feet and has a mix of both sun and shade. Access into the main portion of the park from the campground, is via the California Riding and Hiking Trail.
