Trail Highlights:
Gwin Canyon Trail is an out-and-back hike on a single-track trail in the south end of the preserve. The trailhead is in a neighborhood at the end of a street. Please note, there are only three parking spaces here and no restrooms or other facilities. Most of the trail is shaded. A portion of it runs right above Claremont Avenue and Claremont Creek. There are a few hills on the route, and it may be muddy and slippery in the winter. Be sure to watch out for poison oak along the path.

(To make the hike a little longer, you may continue on Willow Trail into the University of California Preserve lands and make a variety of short loops)
