I bought a DSLR specifically to photograph the Milky Way at Jumbo Rocks. New moon in February, no light pollution south of camp, and 5 hours of shooting. This campground changed my life.

Site 28 has a massive boulder behind it that becomes your living room. Scrambled to the top for sunrise and watched the shadows of the Joshua trees stretch across the desert. Bring good shoes.

This is not a suggestion: bring all your water. There is no water at Jumbo Rocks. We ran short on day 2 and had to drive to Twentynine Palms and back. Minimum 1 gallon per person per day.

Bought a UV flashlight before the trip on advice of other campers. Found 3 scorpions around our campsite at night. They glow bright green. Not stung, but now I always check.
