Scenic, out-and-back singletrack (total almost 10 miles) that can be technical and rocky in some spots. Follows the North Fork Little Laramie River. Starting at Sand Lake Road, the trails is mosty uphill, but mostly easy, to Brooklyn Lake Rd. Then turn around and come back down. You can also shuttle to Brooklyn Lake Rd. to avoid the climb. Trail is well marked and maintained.
Take US HWY 130 west of Laramie. Go six miles west of Centennial and turn right on Sand Lake Rd - Forest Rd 101. After about 2 miles is the trailhead parking area on left, or access the trail from North Fork Campground. Or, go further west on US 130 to Brooklyn Lake Rd - FR 317, take a right and go about 2-3 miles; the trail will be on your right.
