Lone Mountain Trail
What to Expect
Safety Advisory
Big Bend's desert lowlands are among the hottest places in the National Park System. Summer midday temperatures routinely exceed 110 degrees Fahrenheit; the exposed, shadeless character of this trail makes it genuinely dangerous from late May through September.
Rattlesnakes are active year-round in the Chihuahuan Desert. Watch where you step on the rocky sections and never reach blindly under or around boulders.
Trail Details
- 1
Start at first light. The low desert sun paints the Chisos and Rosillos in shades of orange and purple for about 20 minutes after sunrise — a palette you will not see from inside the mountains.
- 2
The trailhead sits off a remote dirt road in the Tornillo Flat area; check road conditions at the visitor center before driving out, especially after rain, when desert clay turns impassable.
- 3
Bring more water than you think you need — at least a liter per person for this short loop. There is no water source on the trail, and the desert radiates heat from the ground even when the air temperature seems manageable.
