Trail guide
Lone Mountain Trail circles the base of an isolated volcanic peak in a 2.7-mile loop, about a mile north of Panther Junction. Expect about 200 feet of elevation change and one to two hours on the trail. It is a good leg-stretch if you are already nearby and want a broad Chihuahuan Desert view; the payoff is open space and mountain scenery, not a long climb or a shaded walk.
Most of the loop is fairly level, with a few gradual rises and dips. The tread sits slightly above the surrounding desert in many places, and the rough sections were built up with local stone. Expect rocks and loose pebbles underfoot; a boulder-field stretch is rougher than the modest elevation suggests. Follow the marked trail rather than cutting across the desert.
The route passes close to Lone Mountain and opens toward the Chisos, Rosillos, and Dead Horse Mountains. Lone Mountain is an isolated peak at the north end of the Chisos, capped with igneous rock over softer shale. The park crew and Texas Conservation Corps shaped the route by hand, moving boulders and rubble to smooth low or steep spots and saving native plants for revegetation.
There is no shade along the loop. Bring water and sun protection; the park recommends one liter of water per person per hour of hiking. Pets are not allowed on park trails. Start at Lone Mountain Trailhead, reached by a half-mile gravel access road about a mile north of Panther Junction; the parking area is small.
