A big steep one mile climb with lots of hike-a-bike followed by a really nice two mile descent. This makes for a good starting trail to ride across the entire network in the Yarmag Hills system. The entire trail is 4.35 miles long if you ride it out to the road, but the last half …

Yarmag Hills

Wild Horses

This is a 4.1 mile climb up the mountain to the top (and back down if you choose to do it as an out and back). It starts as a two track, and after about a mile or so, it dwindles down to narrow singletrack. It is about a 1750′ ascent to the top which …
