We had a fantastic 3 night stay at Aaron’s camp site during Joshua Tree’s in-park camping ban. The sites were secluded enough to feel like we had our own space, and there was more than enough room for 4 tents, 2 cars, and gear with plenty of room left over. Each of the sites have their own individual grills and fire pits, but you may want to pack some chairs as there are only a few at each site. The toilet was great - it had a running toilet, lights, and was very clean.
The camp site is far enough from the main road to feel like open desert camping - we could hear the coyotes at night and even saw a few, beautiful sun rise/set, stars, and moon. The entrance to Joshua Tree National Park was a quick 10 minute drive and very close to town for firewood, food, water, gas, etc.
Aaron is a great host, he responded to all of my questions promptly and even checked in with us in-person once to make sure we weren’t having car trouble.
