Easy to get a permit from the ranger station. Just email your name, address, phone number and driver's license number to sm.fs.mesa_ohs@usda.gov and you'll get your permit within 2 days for free. I love that it's not far out of town but an easy place to forget you live in town. I've seen all types of vehicles out there. Better to have a 4 wheel drive with decent clearance for some of the trails. Most camp spots aren't too deep in so it's easiest to access.
