About The Park
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.

Hayward Marsh, completed in 1985, is a 145-acre fresh and brackish water marsh and is somewhat unusual in that it relies on secondary treated effluent as the freshwater source. The marsh is made up of five managed ponds and has 15 islands that are utilized by many species of nesting birds. Flow through the five basins is controlled by a series of weirs, valves, and channels, and allows for great flexibility in operation, management and biological research.
Oro Loma Marsh was constructed in 1997 and consists of a 364-acre tidal marsh with seasonal wetlands and transitional uplands.
Hayward Shoreline has five miles of graveled public trails along the shoreline.
Levees were originally built in Hayward and San Lorenzo to create land for salt production, Landings were established in the 1850s to ferry passengers and move salt and agricultural products to San Francisco. Remnants of timbers at landing sites along the trail can be seen from the mudflats at low tide.
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.

There is one disabled parking stall at the Grant Ave staging area, but there are none at West Winton Ave. One disabled portable restroom is at the mouth of San Lorenzo Creek next to the information panel. Please make sure to bring drinking water because there are no wheelchair accessible drinking fountains in the park.
