May Your Hike Lead You To Yourself

Mount Williamson is the second highest mountain in the Sierra Nevada Mountain range. If you are looking for a secluded, challenging hike, look no further. Located off the 210 West, take Angeles Crest Highway 40 miles into the depths of the San Gabriel Mountains.

Islip Saddle Day Use Site ("Islip Saddle") lies on the Angeles Crest Highway (CA-2), at the junction of the northern terminus of the now closed Highway 39 (running up the front of the San Gabriel range from Azusa). It is virtually in the middle of the stretch of the CA-2 highway that runs between La Canada / Flintridge and Wrightwood / Cajon Pass, at mile marker 64.10. Islip Saddle has a large parking area on the northern side of the highway, directly across from the now gated and locked end of CA-39. There are restroom facilities and several trail opportunities from Islip Saddle.

The trail to Mount Williamson heads up from the very western edge of the parking lot, next to the restrooms. Be aware of the second trail option on the western end of the parking lot, heading down. This is the upper end of the South Fork Trail. From Islip Saddle, the PCT loops over Williamson's southern shoulder and back down to cross CA-2 at Kratka Ridge. On the crest of the shoulder, at GPS location 34.3660, -117.8602, an obvious use trail heads right (north-northeast), up the ridge to the summit. The trail from Islip Saddle is approximately five miles round trip.
