Marsh Creek Trail follows the sinuous course of Marsh Creek through the outskirts of suburbia and among the rich farmland of Contra Costa County. The 8.5-mile paved extends between Concord Road in Brentwood and Big Break Lake, where the trail intersects Big Break Regional Trail. Where the Marsh Creek Trail crosses Cypress Lane, you can pick up the Delta de Anza Regional Trail

*just north off Central Blvd. where it intersects the trail
*north off Cypress Rd. where it intersects the trail
