You cannot camp for free inside the official borders of Joshua Tree National Park, as all park campgrounds require a fee (typically $25–$35 per night in 2026). However, you can camp for free on the Bureau of Land Management (BLM) lands located just outside the park's north and south entrances. These "dispersed camping" areas are completely free but offer zero facilities—no water, no toilets, and no trash collection. You must follow "Leave No Trace" principles and be entirely self-sufficient. Popular free spots include the "North BLM" (Sunfair Dry Lake) and the "South BLM" near Chiriaco Summit. Keep in mind that during the peak 2026 spring season, even these free areas can become crowded, and you are required to have a California Campfire Permit if you plan to use a portable stove or fire pit.
