The Window Trail is probably the most heavily traveled path in Big Bend National Park, and for good reason. The trail is so aptly named for the framing of the western desert floor by Carter Peak to the south (left) and Vernon Bailey Peak to the north (right). Rain that falls in the Chisos Basin gathers and runs through this opening between the mountains, supporting residents of the park, animals and humans alike. The trail follows this gradual slope down to the opening, crossing arroyos and rolling foothills of scrub brush.
