About The Trail

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 paved, multi-use hiking, bicycling and equestrian trail currently spans over 15 miles of the planned 25-mile length. When completed, it will generally follow the East Bay Municipal Utility District's corridor and the Contra Costa Water District's canal.

This trail is an alternative transportation corridor connecting communities in central and eastern Contra Costa County. It provides access to regional and community parks, many schools and Los Medanos Community College. The community parks have play areas for children and are excellent rest stops during longer trips, providing restrooms, drinking water and picnic facilities.

The trail intersects Antioch's Mokulumne Trail and the Marsh Creek Regional Trail in Oakley. It connects the cities of Concord, Bay Point, Pittsburg, Antioch and Oakley and provides access to Contra Loma Regional Park (and Black Diamond Mines Regional Preserve) through Antioch Community Park.

NOTE: Trail continues. See the Marsh Creek Trail.
