Open year round on BLM lands


The West End of Montrose County contains some of the largest wild tracks of public lands in Colorado and the lower 48. Although there are few singletrack trails here, the Y-11 is the exception. This old cow trail will remain special because of its spectacular location high above the San Miguel and Dolores Rivers, negotiating a sometimes narrow bench with views to be remembered. Riders will also be treated to a birds eye view of the world famous Hanging Flume which is located directly across the canyon from the trail.

Need to Know

Park on either side of the old iron bridge which is closed to vehicles. The new bridge is a mile upstream. Follow the Y-11 road to access the Paradox Valley and Hwy 90. Exercise caution on the Y-11 trail due to high cliff exposure. This trail is unmarked.


The Y-11 can be ridden as a loop or out n' back. To ride the loop, follow CR Y-11 as it follows the San Miguel River towards the confluence with the Dolores River. Past the confluence you'll see a large drainage coming in from the left with a rugged two track coming down.

Follow the two track up for about a half mile until you see a rock cairn marking the Y-11 singletrack coming down from the left. This section is mostly rideable as it climbs up to a broad bench. Here the trail begins the descent back to the iron bridge. The upper section is fast and becomes quite technical as you negotiate this ever changing and challenging trail. Caution should be used as there are more than a couple of exposed sections that the trail gets close to.

For the out n' back, take the trail which can be seen on the south edge of the large open area Follow for 3.5 miles as it gradually climbs the bench and up to where it starts descending into the Saucer Basin drainage. Enjoy some great views before your return back down the trail.

History & Background

The two-track coming down the drainage toward Y-11 road described in the trail description doesn't actually meet the road. Look for a rock cairn on your left, which can be seen from the road. Cross the dry wash near the cairn and follow a single track a short distance to where the two-track starts a steep climb up into the drainage. Oct 13, 2016

This is a neat adventure ride to break up the drive on Hwy 141. I wouldn't say the trail quality is great, but it's worth doing due to the unique nature and excellent scenery. With a little love, it could be amazing. Aug 30, 2017
There is also a spur of the trail leading to an overlook of the confluence of the Dolores and San Miguel Rivers. Well worth the short extra ride. Sep 28, 2017
