The Gabrielino Trail is a United States National Recreation Trail that runs through the Angeles National Forest in Los Angeles County, California. Its western trailhead is at Windsor Avenue in Altadena, California, and it runs generally east/west, with its eastern end at Chantry Flat, just north of Arcadia, California. It passes through three major watersheds. It's suggested as a multi-day backpacking route, but it can be done in a single day by someone willing to push 28 miles in one outing.
The Gabrielino Trail was chosen as the nation’s first National Recreation Trail (NRT) in 1970 because it "represents its region, supports a diverse community, and is among Americas best trails." It's a fantastic trail of nearly entirely singletrack, however, there are sometimes closures of sections of the trail due to fires. Please consult the Angeles National Forest website for details to ensure that the route is fully open before attempting it.
There is a bathroom at Chantry Flats, Red Box, and Switzer Trailhead, but not one at the western terminus. You're running near a creek for much of the run, so there is often reasonably frequent access to water (filtering highly recommended).
Please note that the NE corner of the trail, connecting Newcomb Saddle to West Fork Campground via Devore Campground can sometimes be in rough shape. Much of that section is near a creek bed that can get eroded after winter storms. Check it out beforehand to ensure that it's passable. That said, this is one of the most beautiful sections of the trail and is highly recommended.
