Mountain Biking Stack Rock Loop

  Add a review
#169 of 317 mountain bike trails in Idaho
#11,049 in the world

Ride the single track trail Entrance Exam until you hit Stack Rock Loop. The loops begins with a steep uphill on a wide trail. Near the top the trail is once again single track as the trail loops around a massive rock jetting towards the sky. Enjoy the view and continue the single track completing the loop as you come back to Entrance Exam. Ride Entrance Exam back up to Bogus Basin road.
