We went for the meteor showers in August.... camped at Jumbo Rocks, which is one of the larger campgrounds inside Joshua Tree. It's absolutely beautiful there. Hiking is fun, there's so many trails to follow and climbing the rocks is an adventure. The kids loved it. There are bathrooms, no showers, and we stayed in a tent this time. We have a motorhome, but it's too big to bring inside Joshua Tree. The limit is 35 feet I was told at the main gate. I believe we had to pay $10 for the campsite and also paid an entrance fee, which I can't remember how much that was, but it's a deal. I would go again, but you know what, the Government is closing all State Parks right now, so not sure when Joshua Tree will be open again....but the meteor showers are again this month, so I hope they open soon.
