There are two gift shops with camping areas here. The Petrified Forest Gift Shop on the left heading into the park, has 10 sites with 30amp electricity and a picnic table. $15.98/night. The Crystal Forest Museum on the right has free RV camping. Each site has a picnic table. The owner of the Petrified Forest Gift Shop just purchased the Crystal Forest Museum (which is still closed) and is still allowing free camping on that property. Fires are not allowed in either campground.
This is a small campground next to a gift shop. 10 sites, all with 30amp electric and a picnic table. Nothing special, but it is next to the Petrified Forest National Park. The owner just bought the Crystal Forest Museum across the street. Free camping there with a picnic table and nothing else. No fires are allowed in either campground.
North side of I-40 at the Welch Rd exit. It's a large flat area with a number of established camp sites. Although it's close to the interstate, it's relatively quiet. The north side is bounded by an abandoned section of Route 66. Usable AT&T signal.
Just outside Joshua Tree NP, and just a mile or so from I-10. I-10 is close enough so you can see the traffic, but far enough that you can hardly hear it. Lots of space. Lots of established camp sites with fire rings. The west side has more sites, closer together, better roads. The sites on the east side are more spread out, but some of the roads have softer sand in areas. The land is mostly flat, but not level. It slopes about 3° towards I-10.
We had been boondocking at Joshua Tree BLM South for about a week and needed to come into town to get supplies, empty tanks, etc. So we decided to check out this campground. It was great. Nice view, lot of space, showers (no hot water), trash bins, water spigots (one behind the toilet, 2 more half way between the toilets and the entrance.) $10/night ($8 for vets and seniors) We were there early January 2022. No smell. Some road and train noise, but not bad. It's not level, but not so bad that you'll need to worry about your refrigerator. If you stay at the campground, you can use the dump station at the main campground up the road.
