This is BLM, no designated sites. If you have a 30’ TT you are going to be very limited, but as long as it’s not on a weekend and your creative you’ll probably be ok. Most people drive past the last cattle guard where it starts with the day use parking only, but their are spots before that if you look closely. Theirs the rock pile before the cattle guard and 2 small roads on the left as well. Good luck !
