      Went in with 0 expectations but came out very impressed with J-Boy and all the other trails here. Reminds me of a mini Moab. Very scenic and very good use of the terrain to make the trails super fun and interesting.

      This is a fantastic trail! Utah rated a black, but local rated a double black, since the other stuff around here is pretty easy.

      I love this trail but definitely not a DD line. Assuming this really comes from the rock "bridge", yeah it looks spooky but really low risk or maybe just the high cardio requirement of the climb

      We hope you've been enjoying Trailforks!
