South Rim Trail

The South Rim Trail is a 12.5-mile round-trip loop from Chisos Basin: climb through Laguna Meadows, follow the high South Rim, and return through Boot Canyon and Pinnacles. Allow six to seven hours. It is one of Big Bend’s hardest day hikes, but this is where the park opens up under your feet: the rim looks over Sierra Quemada, the Rio Grande country, and distant peaks in Mexico. Choose it when you are ready for a long day at elevation and want the big, open view; it is not a quick stroll to the rim.

Start at Chisos Basin parking near the visitor center. A short shared approach reaches the Laguna Meadows and Pinnacles fork; take Laguna Meadows first for the gentler climb. Early gaps in the trees look toward Emory Peak and the Window, then brush and woodland close around the trail as the switchbacks gain height. Higher up, openings near the saddle pick out Casa Grande, Mount Huffman, and Peak 6905. At the Blue Creek Canyon junction, stay with the South Rim route instead of dropping into Blue Creek. I would climb this side first and save the steeper Pinnacles descent for the way home.

Above Blue Creek Canyon, the trail follows the ridge between Blue Creek and Boot Canyon. This is the payoff: the view reaches over Sierra Quemada to the Rio Grande cliffs and the mouth of Santa Elena Canyon, with mountains in Mexico on clear days. The rim has abrupt drops, so use established viewpoints and stay well back from the edge. A short, unmarked 0.35-mile round-trip spur reaches a wider panorama; it is optional and is not included in the 12.5-mile base loop. For a photo, keep a little of the rim in the foreground to show how far the desert falls away.

Follow Boot Canyon northwest from the rim; turning onto Northeast Rim makes a longer itinerary, not this base loop. The trail descends to the canyon floor and crosses rocky benches around the wash. After rain, water may run in the slickrock, but Boot Spring is unreliable year-round, so do not count on either for a refill. On the shaded slopes, look for the volcanic spire called the Boot: from the trail it looks upside down, with Crown Mountain behind it.

At the Pinnacles junction, stay on the return toward Chisos Basin rather than adding Emory Peak. The route climbs to a saddle between Emory and Toll Mountain, then drops on long, steep switchbacks through jagged volcanic outcrops, pinnacles, and hoodoos. Views open again toward Casa Grande and Toll Mountain as you lose height. This is a rough finish on tired legs; leave enough time for the descent and do not treat it as a fast walk back.

Bring food and all the water you will need for the day; there is no dependable water on the loop. The park recommends about one liter per person per planned hiking hour, and Boot Spring cannot be counted on. Start early enough to finish in daylight and make room for the long walk out from the rim. Pets are not allowed on Big Bend trails, so arrange care elsewhere.
