The San Gorgonio Wilderness is a federally designated wilderness area in the San Bernardino National Forest, about 25 miles east of the city. Its 58,969 acres encompass two small lakes, mountain meadows, streams, and over 100 miles of trail. Elevations range from 4,400 feet to 11,499 feet at the summit of Mount San Gorgonio — the highest point in Southern California.
The wilderness is managed to preserve its natural character: no mechanized equipment is allowed, and overnight camping requires a permit (available from the ranger station in Mentone). Day hikes are possible without a permit. The trails are good, the mountain scenery excellent, and the contrast with the desert floor below is striking throughout the year.
