We spent two nights here, in our camper van, while visiting the national park. It’s proximity is so great. The area is easy to find, big and open and nearly all up the very upper parts are navigable by a regular car. There are some upper parts that could require 4WD and high clearance. Our only complaints were how dusty is was and that there really were no trees so potentially not much privacy depending whom is camping around you. If you don’t have a bathroom….this could also be an issue. Not much in the way of tree cover if you are going in the wilderness.
We chose sites on the north side of the area, closer to the park and it seemed more private.
