      1 Review & Comments

      Gritty Gritty
      As of 4/29/2022, this trail is primarily used by dirt bikes, which chew up soil and rocks. So DH speed is robbed by spongy dirt. Hence it doesn't seem to be popular with mountain bikers. Also, there are a few downed trees on west side. This trail needs TLC to be MTB worthy.

      We hope you've been enjoying Trailforks!
