Sierra Estrella Wilderness

The Sierra Estrella Wilderness, which includes roughly one-fourth of the Sierra Estrella Mountains, is 15 miles south of the metropolitan Phoenix and east of Rainbow Valley, Arizona. Bordered entirely on the north and east by the Gila Indian Reservation, the Wilderness is only accessible from its western boundary. It contains knife-edged ridge-lines, steep slopes, and rocky canyons, one of the most rugged mountainous areas of Arizona. In the northeast corner, Butterfly Mountain rises 2,600 feet above the desert plain to an elevation of 4,119 feet in only two miles, a challenge for backpackers and climbers. These extreme elevation changes have produced diverse plant communities.
