Hikers then must gradually ascend on the way back. The first mile is through open scrub vegetation with fantastic views of surrounding Chisos peaks. The last mile enters a cool shady canyon with oaks, wildflowers, and a sometimes a trickle of water. It is a narrow slot in the canyon wall at the top of a 100 foot dropoff. This trail is a good one for viewing wildlife.
Hikers frequently see javelina, gray fox, and sometimes even black bears.
For an extra treat, take the Oak Spring Trail which veers off near the end of the Window Trail. The panoramic view from this high vantage point is spectacular. From the Basin Trailhead take the Pinnacles trail for 3.5 miles. At this point, the one mile trail to the summit cuts off and heads upward. Most hikers require approximately 5-6 hours for the roundtrip journey.
