When several existing trails were renamed to make a “new” 28.5 mile (45 km) trail in 1970, in compliance with the National Trails System Act, the Forest Service announcement read as follows:

This trail has been created for you – the city dweller – so that you might exchange, for a short time, the hectic scene of your urban life for the rugged beauty and freedom of adventure into the solitary wonderland of nature.

The trail winds its way from Chantry Flat, through Big Santa Anita Canyon past Sturtevant Falls and Sturtevant’s Camp, then over Newcomb’s Pass into the West Fork of the San Gabriel River. The trail meets the river at Devore Campground then follows the watercourse upstream to West Fork Campground.

To this point, the Gabrielino Trail has been tracing the Silver Moccasin Trail. It is across the stream from West Fork Campground that the Silver Moccasin Trail heads up Shortcut Canyon for the San Gabriel High Country. To continue on the Gabrielino Trail, travel west to the head of the West Fork at Red Box Saddle near Mount Wilson. This is the trail’s highest point.

From Red Box, the Gabrielino continues westward down the Arroyo Seco through Commodore Switzer Trail Camp, Oakwilde and Gould Mesa Campgrounds, and emerges from The Arroyo at the Jet Propulsion Laboratory.


Potable water is available at the Chantry Flat trailhead, but otherwise one must boil or filter the stream water. Very little cell phone service along the entire route.
