"This trail provides a spectacular introduction to the beauties of the desert. The interpretive brochure and the clear signs will help you become familiar with the plants and animals, geology, history, and ecology here. Ocotillo abound, as do honey mesquite, cheesebush, and chuparosa––the “hummingbird plant.” Hummingbirds are plentiful, especially in spring. In winter and spring, water flows in the adjacent stream, with small waterfalls. Sharp-eyed hikers may spot reclusive bighorn sheep on the canyon’s mountain slopes, especially in early morning or evening. The trail begins at a pupfish pond, which holds the minnow-sized remnants of a prehistoric lake population."
