South Rim via Pinnacles and Boot Canyon Trails (and Emory Peak) Professional Review and Guide
"The Pinnacles Trail climbs into the Chisos Mountains to the South Rim, a sheer escarpment on the south side of the high section of the mountains. Views encompass thousands of square miles of desert and mountains, making this one of the most impressive hikes in the park.
From the Basin, the Pinnacles Trail climbs steeply through oaks, pines, junipers, and madrone trees to a high saddle between Toll Mountain and Emory Peak. At this pass, the trail levels out. From here, spectacular views of the Basin, the Window, and the desert far to the west attract the eye. The junction with the Emory Peak Trail lies about 0.1 mile down the trail from the saddle; bear left unless you wish to climb Emory Peak.The right-hand trail, a 1-mile spur, leads to the summit of Emory Peak, the highest point in the Chisos Mountains. It climbs steeply and requires a bit of rock scrambling at the end. Sheer, vertigo-inducing cliffs drop off from the summit on several sides. Views from the summit cover 360 degrees and encompass almost the entire park and far beyond."
