Three Points to Vetter Loop

This 16.6-mile loop begins at the Three Points Trailhead along Angeles Crest Highway and winds through the San Gabriel Mountains to the historic Vetter Mountain Lookout. The route blends shaded forest trails, open ridgelines, and sweeping views of the San Gabriels, making it a full-day adventure for hikers and trail runners seeking solitude and steady elevation gain.

From the Three Points Trailhead, the route follows the Silver Moccasin Trail south towards Chilao Campground passing through mixed conifer forest and chaparral-covered slopes. The trail climbs gradually along ridges with occasional glimpses of Mount Waterman and Twin Peaks. 

Continue toward Vetter Mountain Road for the climb to Vetter Mountain Lookout. The lookout provides panoramic views across the San Gabriel Mountains, with Mount Baldy, Strawberry Peak, and the Los Angeles Basin visible on clear days. The restored fire lookout tower is a historic highlight and a perfect place to take a break.

To complete the loop, descend via Vetter Mountain Road and follow Mount Mooney Truck Trail north, eventually reaching Angeles Crest Highway. Cross the highway, reconnect with the Silver Moccasin Trail and retrace your steps back to Three Points.
