How You Can Help

For All of Us

One of the last urban shoreline nature preserves is under threat from city planning and a lack of funding. We need our entire community to understand the value of this magical place and contribute in any way possible. Please donate, volunteer and join our newsletter to stay informed.

We Have the Power to Impact Our Future, and We’re Doing Something About It

Founded in 1854, the Mare Island Naval Shipyard is the oldest Naval installation in the Pacific, and the start of a 142 year legacy of dedicated military service and a rich mixture of historic resources. On April 1, 1996, Mare Island Naval Shipyard officially closed.

Vast natural habitats and a summit of panoramic vistas span seven counties and create stellar views of Mt. Tamalpais and Mt. Diablo and the East Bay hills. Inlets and surrounding salt marshes protect rare plants and habitat. Shorelines, piers, wetlands, coastal chaparral and grasslands attract and support a wide diversity of wildlife.

Located within this historically endowed site is the Naval Ammunition Depot (NAD) historic district, including munitions storage magazines, some of the oldest homes on Mare Island and the U. S. Navy’s oldest cemetery in the Pacific. The National Park Service recognized Mare Island’s exceptional value when it designated Mare Island as a National Historic Landmark for representing a century and half of both American military history and the maritime heritage of the United States.

Today the park’s purpose is simply the enjoyment of the public and protection of history and nature resources. We offer limited camping which is a source of revenue for park operations. Nature Tourism is also an important element of our mission. We are also home to yearly events like the Lost Boats of Mare Island, the San Francisco Bay Flyway Festival and a Halloween celebration in our cemetary and bunkers.

Unfortunately, the Mare Island Shoreline Heritage Preserve has not yet received the funding it was promised by the City of Vallejo. Volunteer and in-kind support from corporate employees, governmental agencies and civic groups help maintain the property.
