Forsythe Canyon Trailhead

Forsythe Canyon Trailhead provides access to the Forsythe Canyon Trail and parking for the Winiger Ridge area west of Gross Reservoir. Gross Reservoir is managed by Denver Water. Visit their website for regulations and information. The Forsythe Canyon Trail (#852) is a non-motorized hiking trail. From the Forsythe Canyon Trailhead, walk downhill from the parking area. The trail begins near the gate on National Forest System Road 359. Forsythe Canyon Trail leads off of a rocky point, following Forsythe Creek down its wooded, rocky canyon. The small creek runs noisily in spring, forming small, picturesque waterfalls and cascades finally ending at the far northwestern tip of Gross Reservoir.
