The East Fork Trailhead provides access to the East Fork of the San Gabriel River via a popular 5-mile hiking trail featuring multiple river crossings and scenic canyon views.

The parking lot fills quickly on weekends, especially during the popular November-May season, and an Adventure Pass or America the Beautiful Pass is required.

The river offers swimming opportunities in summer and leads to the historic Bridge to Nowhere, with several primitive campsites available along the route for backpacking.
