The Reservation Divide trail above the Ninemile valley, preferred direction is east to west. This is rugged, difficult riding and involves a good amount of hiking so be prepared. To start out you get a very steep climb to near the top of McCormick peak that you will be walking, but then does get better and is mostly ridable after that. There is little/no water along the trail and expect to take 5+ hours to cover the distance from the start of the trail to Seigel pass. To do the entire trail a shuttle is helpful, but by riding up the road and then descending the ridge early at Burnt Fork you can ride a shorter complete loop of about 35mi.

Access Info

From the Ninemile valley ride or drive to the top of McCormick Creek road to reach the eastern end. The western end is above Seigel pass.
