South Fork is a standard route for accessing the 10,000 ft ridge, San Gorgonio etc. I did a single night backpack trip to the High Meadow Spring. Got up the next morning and hiked out to a couple peaks, then picked up my pack and returned. Great views and a wonderful campsite at High Spring Meadow that is very comfortable and out of the wind. This can also be a first stop on a great two-nighter bagging Mt. San Gorgonio. Water is rare up here, so I like that I can do the whole trip with only a liter of water on my person. The trail is moderate until one reachs the Dry Lake trail junction. From that point, it's steeper. the total ascent takes at least 5 hours and comprises about 3,500 ft elevation gain. The remaining elevation was bagging Alto Diablo, Shield Peak and Anderson Peak to the west.
