DAY/BACKPACKING OVERVIEW: This is a moderate trail. The trail is used by mountain bikers, hikers, and horseback riders.

ACCESS: This trail can be accessed from either the Thomas Lakes trailhead below Mount Sopris or from the BLM parking lot off of Capitol Creek Road. This narrative is from the BLM parking lot: Drive 14 miles west of Aspen on Highway 82 to Old Snowmass and turn left. Continue 2 miles to the “T” intersection. Take the right turn and continue 5 miles until the pavement ends. Follow the dirt road about 1.5 miles to the BLM parking area, which is off to the right. There are limited camping opportunities on this trail as it is primarily a day-use trail.

NARRATIVE: From the parking lot the trail climbs uphill through a wet pasture and travels along a fence line for approximately 1,000’ until you reach the bulletin board and trail sign. From here the trail winds steeply and crosses through private property for approximately 1.2 miles. It is important to stay on the trail and follow directional signing for the Hay Park Trail. Once on National Forest land, the trail drops and climbs and crosses several small streams such as Hardscrabble Creek and then East Sopris Creek (2.2 miles from start) where there is a small footbridge. The trail travels through many Aspen groves as well as a few stands of pine and spruce trees. The highest point on the trail is the subtle pass in Hay Park at 9,680’. This route is popular with horseback riders, mountain bikers, and hunters in the Fall.
