Northwest of Fort Collins and Red Feather Lakes, there is a network of Forest Service roads open to dirt biking.
The best trailhead is just to the west of Red Feather Lakes. Follow Deadman Road (CR162) for about 3.5 miles up the switchbacks and look for the trailhead on the left side of the road for the popular Killpecker route.
Some of these the trails shown on this map overlap with the trails shown on the Green Ridge map.
Note: Colorado residents must register their off-highway vehicle with the Colorado State Parks (303) 866-3437.
