The Green Rock Trailhead provides the easiest way to get to both the Barber Lake and Libby Creek Trails. The Barber Lake Trail works its way downhill toward Barber Lake. The lowest portion of the trail is a road which provides access to some private residences. Libby Creek Trail takes off from Barber Lake Trail and follows the ridge over Libby Creek for a little over a mile before dropping down toward the creek and heading back to Barber Lake Trail.
Green Rock Trailhead is at the high point for both trails so unless you start from the Barber Lake Picnic Area you will be walking up hill on the way out.
