Big Break Regional Shoreline, part of the so-called “Inland Coast” at the mouth of the massive San Francisco/San Joaquin river estuary, was once a massive farm, now submerged. It is now part of the East Bay Regional Park District.
Most park users come simply to enjoy cool marine breezes in summer. Bass fishing is the most popular recreational activity, but hikers, bikers, dog walkers and equestrians can explore along the Big Break Regional Trail, which runs along the park’s southern edge.
Dogs must be leashed and stay on the trail, but that shouldn’t inhibit your enjoyment of this off-the-beaten-track slice of shoreline.
The Big Break Regional Trail connects to the northern end of the Marsh Creek Regional Trail, providing access to Brentwood and Oakley. The Marsh Creek Regional Trail connects to the Delta de Anza Regional Trail via West Cypress Road, providing access to Oakley, Brentwood, Antioch, Pittsburg and Bay Point.
The park district’s newest visitor center is in the area of the park accessible from Big Break Road.
Dogs must be leashed and stay on trails when visiting this park. Please pick up after your dog!
