The "Outer Mountain Loop" refers to the 30-mile circuit that combines the Pinnacles, Juniper Canyon, Dodson, Blue Creek, and Laguna Meadows trails. It includes a wide variety of habitats and scenery including, the piñon/juniper/oak woodlands of the Chisos Mountains and the surrounding Chihuahuan Desert. Sections of this trail are extremely steep and there is limited flat or level hiking. The route is extremely strenuous and is not recommended for inexperienced hikers.

Most hikers begin from the Chisos Basin and hike the trail in a clockwise direction. Bear-proof storage boxes are available for caching water at two locations only: The Blue Creek/Homer Wilson Ranch on the Ross Maxwell Scenic Drive and the Juniper Canyon Trailhead (high-clearance vehicle required). Caching water or other items for use on the Outer Mountain Loop in the storage boxes at Toll Mountain Pass (upper end of the Pinnacles Trail) or any other NPS-provided storage box is prohibited.
 

Safety Concerns

  • Each year, park rangers are called to respond to medical emergencies along this route. Most are the result of severe dehydration and heat-related conditions.
  • Backcountry permits are required for all overnight backpacking in Big Bend National Park.
  • Cell phone service is limited in the park. Always have a friend who knows your itinerary and can call the park if you are overdue.
  • Please, do not attempt this hike during the summer months. From early May through early October, it may be physically impossible to carry enough water to safely hike this trail.
 

Caching Water

Carrying adequate water is always a concern on this trail. Do not rely on seasonal or intermittent springs. We recommend that you carry a minimum of one gallon of water per person per day. Water can be cached in the storage boxes located at the Homer Wilson/Blue Creek Ranch and at the end of the Juniper Canyon road (Juniper Canyon requires a high clearance vehicle). Caching water in any other NPS-provided storage box is prohibited.

When caching water, remember to mark each bottle with your name and the date you plan to pick up the water. Please pack out empty bottles. Only water can be stored in the storage boxes. Food and equipment left in the boxes are subject to removal.
