It’s like mountain biking through Bryce Canyon National Park, if that were allowed
Not actually in the national park (biking off the paved trails there is not legal), this ride is close to the park and meanders through pine forests then whips around real hoodoos (sandstone towers) before taking a wild descent. It is a bit of a climb, but oh so worth it.
Thunder Mountain tops my list of all time favorite mountain bike rides. I liked it so much that after I did it with my family, I flew out in my small plane with a friend and we rode our bikes from the Bryce airport just to do this ride.
You can do this as a loop in which case you ride on the bike path along highway 12, or you can shuttle past the road part.
