This Delta de Anza Regional Trail is named to commemorate the route taken by Spanish explorer Juan Bautista de Anza during his 18th-century expedition into the Delta region of today's East Contra Costa County.
The Alameda Creek Regional Trail follows the banks of Alameda Creek in southern Alameda County from the mouth of Niles Canyon (in the Niles District of Fremont) westward to San Francisco Bay - a distance of about 12 miles.
When complete, this trail will connect two of the Park District’s largest open space parks. The existing portion of this trail links Briones Regional Park to the Lafayette-Moraga Trail in the City of Lafayette.
One of the most popular trails in the Park District system, this multi-use, whole-access trail (accessible to persons in wheelchairs) is a paved pathway suitable for bikers, runners and equestrians.
