The good news is that you do NOT need to book a permit or a reservation to camp in the wilderness at Joshua Tree National Park!
I chose the Twin Tanks board because it’s right across from the Arch Rock area which I wanted to explore.
Once you leave your parking lot you need to hike at least one mile away from the parking lot and at least 100ft away from a trail or water source before setting up your tent.
The Arch Rock Nature Trail begins here and the Arch Rock itself is towards the right.
