My son and I spent a night here and it was great! I’d recommend south prong primitive sites. Got to sleep right at the base of the canyon and there was plenty of space between the campsites.
My only problem was that some of the trails were not very well marked. It took us a while to find the right trail heads and even longer to find some of the more scenic sites (You’ll walk right over the natural bridge without realizing it!).
Overall, was very happy and will definitely come back.
Oh! And there are bison everywhere! Super cool.
