June 18, 2025, Valle Verde Trailhead Lafayette

Valle Vista is the trailhead for the paved Lafayette-Moraga Regional Trail, a popular rail-trail for cyclists. There’s a restroom here, but note: the EBMUD dirt trails are hiking-only and require a permit. The bike trail has been officially closed between here and Moraga since a 2019 landslide.

This trailhead begins at the Contra Costa Canal Trail junction. Most of the trail runs along the Ygnacio Canal, where you'll likely see plenty of ducks who inhabit the area. Most of the trail is paved, however, there is an unpaved section near Ygnacio Valley Rd.
