The Dog Run Hollow Trail System, a part of the National Recreational Trail System, has trailheads at French Lake, Boulder, Lost Lake, and the Dog Run Hollow parking areas. Using the French Lake trailhead, visitors can choose among a one, three or four-hour hike through some of the more unique areas of the refuge. The Elk Mountain Trail System is made up of two trails. One leads hikers through the Charon's Garden Wilderness Area and ends at Post Oak/Treasure Lake parking area, while the other leads to the summit of Elk Mountain. From the top of Elk Mountain, hikers will enjoy a spectacular view of much of the refuge. Another trail leads from the Quanah Parker Lake dam to the summit of Little Baldy Mountain and a side trail from the Doris Campground joins the trail on the western edge of the lake.
