Some of the finest singletrack in Summit County.<br />
This loop combines singletrack, double track rec. path- and ok- a little road into a loop around Dillon Reservoir. I usually start the ride from Keystone but you can start just about anywhere. The basic route is: Aqueduct>Blair Witch>Colorado Trail>Peaks Trail>Rec. Path>Old Dillon Reservoir>Oro Grande. For more mileage you can add Frey Gulch and West Ridge.
From Denver take I-70 west to the Loveland Pass exit #216 follow Hwy 6 over Loveland Pass to Keystone (about 12 miles) turn left on Gondola rd. (the first the left you can make just past the overpass) follow East Keystone Rd. to the end and park.
