Tree Zone Exhibit

Tree Zone Exhibit is a roadside interpretive stop on Chisos Basin Road, where the climb into the Chisos begins to enter woodland. Step out to read the panel and look across the shaded drainage toward the mountains. The NPS lists the wayside as wheelchair accessible. It is a brief pause to understand the landscape on the way into the basin.

Here, sotol and cactus grow alongside oaks, junipers and piñon pines. Look across the hillside for the transition: the exhibit is about how vegetation changes with elevation, not a single tree or a sharp boundary.

The north-facing drainage is shaded beneath an oak, and the NPS calls out Mexican jays here. Pause to listen and take in the mountain view. For a photo, include the wayside's low stone wall and panel in the foreground, with the oak and rocky slopes beyond.

The Civilian Conservation Corps built Chisos Basin Road in the 1930s, and it rises more than 2,000 feet above the desert floor. Its curves and grades can reach 15%; the park advises against trailers longer than 20 feet and RVs over 24 feet.
