>>838087I did this in arches, I hiked up courthouse wash, which is the largest part of the park that permits primitive camping (but you need a permit which I didn't have), then once I reached the end of the wash I was near the middle of the park. I hiked through the petrified dunes, which was probably the coolest place I've ever seen, and idk what the rules are regarding that. But it was really hard because I didn't wanna step on the cryptosoil like an asshole so I had to jump around alot. I camped another night there and then walked toward the windows area of the park. The next day I checked out the windows and by then I had run out of food and water so I started hiking back out via the road. It was getting dark so I started thumbing and lucky for me I got a ride out, otherwise I might have gotten busted. All in all I highly recommend doing this as long as you are willing to suffer by not stepping on the cryptosoil. I mean I recommend it as a hike but its risky as far as the law. Petrified dunes were like an alien moonscape. I found shallow caves hollowed out from big dunes that had flakes of flint left over from the Indians.
