Directions from Granby: Take Highway 40 west to Highway 34. Go north on 34 to County Road 4, near the north edge of Lake Granby. Take County Road 4 northwest to the intersection of Forest Roads 120 and 123. Go left on Road 123 and follow about 6 miles to the Gilsonite Trailhead sign.

Really sorry to hear about the bad experience Preston! I noticed the sign on the road for the trail today and had a great time.

Whoever said the southernmost point of Gilsonite starts from County Road 4 according to the map should be shot. I’m here now and there’s no wooden signs, can’t see any path into the forest, nor any tree markers. This is a wild goose chase. Someone delete this trail from the app, asap.
