ER7 is a backcountry campsite in Big Bend's Chisos Mountains, located 6. 5-8 miles from the Chisos Basin Trailhead via the Pinnacles or Laguna Meadows Trails at 7,400 feet elevation.

This large group site accommodates up to 10 people across 5 tents and features good tree cover, wind protection, and spectacular panoramic views from a nearby "front porch" area overlooking the Sierra Quemada desert.

Note: The East Rim Trail is closed February 1-May 31 to protect breeding peregrine falcons.
