Southern California boasts a remarkable landscape, a rich mosaic of mountains, deep canyons, and desert fringes. Among these natural wonders, the San Bernardino Mountains stand out, offering delightful pathways such as the picturesque route to Heart Rock Waterfall. Dominating this spectacular terrain is San Gorgonio Peak, a landmark once referred to as \"Old Grayback\" by locals, holding the distinction of being California's highest point situated to the south of the Sierra Nevada range. While the challenging Vivian Creek Trail offers unparalleled vistas for those who dare to ascend, numerous scenic viewpoints are scattered throughout the San Gorgonio Wilderness. This area is home to a rich variety of deciduous trees, including California's southernmost aspen grove, making its extensive network of trails exceptionally beautiful during the autumn season.
The San Gorgonio Wilderness encompasses an impressive 81 miles of trails, featuring a segment of the well-known Pacific Crest Trail. Additionally, it provides 24 complimentary backcountry campsites and numerous other reservable sites within the San Gorgonio Campground. Whether your visit involves an overnight stay or a day-long trek, this pristine wilderness offers an exceptional setting to witness the magnificent autumnal palette.
For the most spectacular views, head to the aspen grove, located approximately half a mile into the Aspen Grove Trail. The presence of aspens here might seem unusual, given their preference for cooler climates, but the San Gorgonio Wilderness offers a surprisingly temperate environment compared to other parts of Southern California. During autumn, the aspen leaves transform into a brilliant golden-yellow, occasionally tinged with red, with their peak vibrancy typically occurring in the first half of October. Beyond the aspens, you'll encounter a rich display of black oaks, big leaf maples, and sycamores, all contributing to the trail's stunning fall coloration.
The San Gorgonio Wilderness can be accessed via several entry points, each leading to different trails. The Aspen Grove Trail provides its own dedicated parking area off forest road 1N05. If you're arriving by air, San Bernardino International Airport serves as the closest commercial hub, roughly a 2.5-hour drive from the Aspen Grove Trailhead. It's important to note that the forest road may be inaccessible during winter months.
A permit is required for all hikers entering the wilderness, with the exception of certain areas managed by the Bureau of Land Management rather than the Forest Service. These permits are free and can be reserved online; however, they are highly sought after and often sell out quickly on autumn weekends. Once on the Aspen Grove Trail, a short 0.75-mile walk, after crossing a creek and turning right, will lead you to the heart of the grove. Several popular trails, including the Vivian Creek Trail, originate from Forest Falls, a community located just a 30-minute drive from San Bernardino International Airport. The months of September and October are ideal for those wishing to conquer the steep Vivian Creek Trail.
From winter to early summer, the elevated sections of the trail can become perilous due to unpredictable and severe weather conditions, including the risk of fires. Additionally, snow typically begins to fall on the trail from mid to late autumn. The Momyer Creek Trail, stretching over 4 miles and also commencing from Forest Falls, presents another excellent hiking option for the fall season, when temperatures are more pleasant and the glistening creeks are at their fulles
