The Antonovich Trail is a 3.8-mile trail that descends into a canyon then follows a stream to a flood control channel. With portions that are difficult and others that are flat and wide, this trail offers a variety of experiences for users to choose from.

This trail is a popular trail that has experienced a large amount of visitation since trails reopened on May 9, 2020. If the San Dimas Avenue Trailhead parking lot is full, do not park along the street. It's recommended that you park at the Valley Center Staging Area & Trailhead (1100 S. Valley Center Avenue, San Dimas, CA 91773) or Lyman Staging Area & Trailhead where you can find ample amount of parking and shade alongside Walnut Creek.
