The Delta de Anza Regional Trail is 15 miles long, running between Willow Pass Road at Route 4 near Concord and Main Street (Rt. 4) at E. Cypress Road in Oakley. The eastern end in Oakley intersects Marsh Creek Trail
. The trail also intersects the developing Mokulumne Trail
by Antioch Community Park. There is a break in the trail between Neroly Road and Ridgeline Drive.
The trail links neighborhoods, business districts, schools, parks and the Los Medanos Community College. In the parks you'll find plenty of rest areas, restrooms, drinking fountains and picnic areas. There are plans to extend the trail another 10 miles, including west to Martinez.
The county reports that the trail is mostly wheelchair accessible, though some sections can be steep, particularly those adjacent to Los Medanos College and Marchetti Park in Pittsburg and segments on both sides of Canal Park in Antioch. The trail over the Willow Pass in the direction of Evora Road in Bay Point to Willow Pass Road in Concord is long and steep.
The Delta de Anza Trail is named commemoration of the route taken by Spanish explorer Juan Bautista de Anza during an 18th-century expedition in the region.
