Ascend the forested Pinnacles trail for 3.5 miles to the Emory Peak trail junction (on your right). Then take the 1-mile spur trail to the peak which has nice vistas along the way. The last quarter mile or so climbs steeply, and the last 25 feet require a scramble up an exposed rock face, but the 360° view from Emory Peak, the highest point in the park, is superb. The antenna and equipment are part of Big Bend's two-way radio system.
