South Rim 3 is a primitive hike-in backpacking campsite located 5. 6 miles from the trailhead via Laguna Meadows Trail in Big Bend National Park's Chisos Mountains, accommodating up to 10 people with excellent panoramic views of the desert and Mexico.

The site offers adequate shade but is exposed to wind, with no water available—hikers must carry at least one gallon per person per day.

Important requirements include packing out human waste using a disposal kit (burying is prohibited on the rim), using bear boxes for food storage, and no fires or hammocks are permitted.
