The Window

The Window is the narrow rock pour-off at the west end of Oak Creek Canyon, where the Chisos Basin drains toward the desert through a cleft in the rim. The classic view looks out through that gap from the top of a roughly 200-foot drop. This is the destination at the end of a hike, not the short paved Window View near the Basin visitor services.

From the main Chisos Basin trailhead, the hike is 5.5 miles round trip with 1,000 feet of elevation change, about three hours. You go down first, then face the long climb back. Start early to avoid the daytime heat.

The main route begins by the Basin Store, near the Visitor Center parking lot. There’s a shorter approach from near campsite 51: NPS lists it as 4 miles round trip with 600 feet of elevation change, taking about two to three hours. For that start, use the Amphitheater parking lot across from the campground entrance, not a campground space. Pets aren’t allowed on park trails.

The trail drops from open chaparral into a shaded creek bed beneath tall canyon walls. Near the end, stone steps pass pools, then the last quarter-mile follows slickrock. That finish can be slippery when wet; in wetter periods, Oak Creek may be flowing and the route crosses it several times. The return climb is the part to save energy for.

At the pour-off, the rock opening frames the desert below. Keep the gap in your composition so the view reads as a window rather than another canyon scene. The Oak Spring spur adds about a quarter-mile walk to an elevated view back toward the opening, with the Chisos and desert in the frame.

The Chisos look like the rim of a huge crater, but NPS says there apparently was no volcano in the Basin itself. About 38 million years ago, volcanoes to the south and east spread ash and lava here, while magma that never erupted cooled underground. Erosion stripped away softer rock and left resistant rhyolite intrusions as many of the mountains around the Window.

Rain falling in the Basin drains down Oak Creek, gathers in smooth pools above the pour-off and drops about 200 feet to the desert. The shaded creek bed and cliffs are part of the visit, not just a lead-in to the final view.

The canyon sits in a cooler, wetter pocket above Big Bend’s desert lowlands. Mexican pinyon, drooping juniper and several kinds of oak grow in the high country. Packrat middens near the Rio Grande show oaks and junipers growing much lower about 10,000 years ago; as the climate warmed and dried after the last glacial period, those plants retreated to cooler mountain areas.
