Horse Riding

Forsythe Canyon Trailhead offers access to the Winiger Ridge area west of Gross Reservoir. Forsythe Canyon Trail is the only non-motorized trail; it is one mile in length. Miles of roads offer great opportunity for riding when the seasonal gate is closed. Parking is available outside of the seasonal gate for year-round non-motorized access.
