Land Owner
A ride with some of the more rewarding descents in the area although be prepared to work for them. Walker Ranch is most notable for fast loose descents followed by steep leg and lung busting climbs. Be prepared for a mandatory hike-a-bike section as the trail heads down to South Boulder Creek.
