Hello, if you are in inside Joshua Tree National Park and paid an overnight camping fee which is about $30 at any of the multiple camp sites then yes restrooms are available at every site. dispersed camping is not allowed inside the national park. Outside the national park restrooms are not available, visitor center inside the park has a detailed map to find the closest facilities

There are no bathrooms or toilets in this dispersed camping area. You'll want to bring your own environmentally friendly toileting solution. Campendium has some proper waste disposal tips here: https://www.campendium.com/camping/leave-no-trace-boondocking/

There are no porta-potty setups. To avoid a growing human waste problem from tent camping (Sorry, gross, but real issue) you can purchase a mobile composting toilet for camping.

Yes, the previous answer is correct. When "boondocking" you'll have to have a place to go or bring a privacy tent and portable toilet. Have fun...

There are no bathrooms at this “campground”. It is public land outside the south entrance of the park. You will need to have some kind of accommodations for yourself. There are bathrooms at the visitor center a few miles up the road but I don’t know when/if they are open.

Well we had a revel sprinter van which had a toilet in it. But I suggest that you have a shovel and you walk far away from people and dig a hole deep and cover and leave no trace. The trail heads of the well-known hikes might have Sanicans or restrooms. I hope people who actually didn’t have toilets in their vehicle can help you a little bit more but it sure is beautiful out there.

No restrooms at all, it’s basic camping. There were tent campers and they were doing their business in nature.

We’re in an RV, so our restroom situation is all set. But for tent campers, the Chiriaco Summit Chevron station is nearby, with facilities available to the public. We also know people who have portable camp toilets with disposable receptacles. A truck is bonus because you can keep it in the bed. Happy camping!

There are no restrooms here so will need to pack out waste. We’ve used a pop up tent before but this is our current bathroom set up: https://www.outbackescapades.fun/gear/camping-toilets-lets-do-this

The last time I visited, there were no restroom facilities nearby without a drive into the park itself. There's a post on the Campendium blog about how to handle bathroom waste if you're tent (or truck) camping: https://www.campendium.com/camping/campers-guide-to-human-waste/
