Hayward Regional Shoreline consists of 1,811 acres of salt, fresh, and brackish water marshes, seasonal wetlands and public trails.

Cogswell Marsh, a 250-acre tidal marsh restoration and enhancement project, was completed in 1980. This area, once restored to tidal action, rapidly became an established saltwater marsh.

Please note: In order to protect wildlife, dogs are not allowed south of the West Winton Avenue flood control channel.

Activities at the shoreline include hiking, bicycling, jogging, birdwatching, picnicking and fishing. Fishing is allowed from the levees, except in the marsh areas. A California State Fishing License is required for those age 16 and over.

Picnicking is permitted, but there are no picnic tables at the park. Benches are located along the trail. Dogs are not allowed south of Winton Avenue to protect nesting and feeding wildlife.

Please remember during your hike or bicycle ride that many shoreline areas provide nesting habitat and feeding grounds for wildlife. In order to minimize human intrusion, please remain on the trail and observe specially signed restricted areas.

Dogs are welcome in the park on a leash. No parking fees.
