Wilderness Landscape & Natural Heritage
The San Gorgonio Wilderness Area encompasses approximately 94,000 acres in the San Bernardino National Forest in Southern California. It is centered around Mount San Gorgonio (also known as Old Greyback), which rises to 11,503 feet, making it the tallest peak in Southern California and the Transverse Ranges. The wilderness’s geography includes steep granite ridges, dense conifer forests, and high alpine meadows, transitioning down through chaparral and desert scrub at lower elevations. This diversity creates habitats for wildlife such as mule deer, black bears, mountain lions, bighorn sheep, and numerous bird species.
Historically, the area was inhabited by the Serrano Indians and later became a focus for conservation efforts, designated as a wilderness area in 1964 under the Wilderness Act. It serves as a natural refuge in a highly developed region, offering visitors solitude and rugged beauty. Key recreational activities include long-distance hiking on routes like the Haywire Grade Trail and the Vivian Creek Trail, camping at backcountry sites, mountaineering to the summit, and wildlife observation. The wilderness’s remoteness and challenging terrain make it popular among experienced outdoor enthusiasts seeking tranquility and a rigorous experience. Nearby landmarks include the San Gorgonio Mountain Summit and nearby San Bernardino Peak, providing panoramic views of Southern California’s mountains and deserts. Its relatively cooler climate compared to the surrounding desert makes it a favored summer escape. The wilderness is maintained by the US Forest Service and requires outdoor users to practice Leave No Trace principles to preserve its natural integrity.
