In the Chisos Mountains of the 800,000 acre Big Bend National Park, the South Rim Trail runs above 7,000 feet and offers views that reach far into Mexico. The 13-mile loop begins in the Basin, a mountain valley walled in by reddish-brown igneous rock; you can hike in either direction, but the Laguna Meadow Trail climbs less steeply on the outbound leg. Dont pitch your tent right on the rim, especially if its windy. On the return, descend the Boot Canyon and Pinnacles Trails. Plan on at least two days, so you can hike to Emory Peak, the areas highest summit, and the North Rim, an extension of the South Rim.
To reach the trailhead from El Paso, take US 10 east 119 miles to US. 90. Go south for 104 miles to Alpine and SR 118, and then 100 miles to the Basin Visitor Center.
Overall, South Rim is the 6th most popular hiking trail of all 32 hikes in Texas.
