Exit I-70 at Exit 176 (Vail) and head west on the North Frontage Road for 1 mile to Red Sandstone Road, turn right and follow the paved road for 3/4 miles. The paved road switches to the right and a graded dirt/gravel road (FS 700) continues on from this point (signed). If muddy 4WD is recommended, but the road is usually fine for 2WD vehicles. Follow the road for 11 miles to the parking area just before the entrance to Piney River Ranch. The ranch is private, there is a public trail that skirts it which starts across the road. There is some dispersed camping along the road.
Road is not maintained, gated and locked about 1/2 mile up the dirt road, usually until at least Memorial Day. Do not park in front of the gate, there is a paved parking lot at the bottom of the hill you can use but is limited to 3hrs. Watch for snowmobiles on the road.
