Trail shared by David Jones

Fun trail that will test your fitness and aerobic capacity. Challenging uphills, great downhills, a little technical.

A great singletrack that offers a little bit of everything. Well-formed switchbacks, inspiring rides through old growth forest, and sidehill tracks across open meadows offer great views of Summit County. There's a long downhill on the Red Trail that in the springtime is guaranteed to get your feet wet on very rideable stream crossings. Blair Witch offers a constantly changing environment with "little beavers" building log obstacles across the trail. It ends with a great downhill on the Colorado Trail.

Need to Know

During heavy tourist season, this free parking lot will fill.


Starting at the popular Tiger Road Dredge Trailhead, this trail starts climbing at the Colorado Trail intersection for the next 2.5 miles. This section has switchbacks, short (sorta) steep climbs, on a reasonably smooth surface. There are a few short sections of rocky/rooty climbing. Trees dominate except the small beetle kill clear-cut areas.

While riding through the flatter old growth forest area, you get a breather while enjoying the atmosphere. After the 750-foot elevation gain you get a sweet downhill, but the climbing is not over yet. Now comes some sidehill sections in open meadows challenging you to either look at the narrow trail or the scenery.

After joining the Red Trail, there is another 0.5 miles of easy climbing, then another 0.5 miles of flats through the forest before hitting the only technical drop on the ride. Make sure you look close before riding over it. Now you get a 2.5-mile downhill with several stream crossings, all rideable.

At the end of the Red Trail, hop over the the Hay Trail for a mellow 1-mile climb to the start of Blair Witch. Blair Witch is totally in the trees and has lots of turns, climbs, and downhills. The lodgepole pines used for the features are not very durable and the very rideable log features are being constantly replaced.

The last section is the Colorado Trail right at the exit of Blair Witch. It is mostly downhill from here. Try to refrain from locking up the rear brake and eroding the trail. Hope you enjoyed it.

History & Background

The trailhead is at the Tiger Road Dredge, one of the few remaining areas miners use to mine gold and other valuable minerals. It is still mostly intact. The start of this ride is through large rock tailings leftover from the mining era.
