Mare Island Shoreline Heritage Preserve


For outdoor enthusiasts, history buffs, photographers and artists, the southern "original" Mare Island Hill and Historic Shoreline is an unique parkland. On behalf of the Mare Island Heritage Trust, I invite you to hike, bike, explore, paint, contemplate, picnic and participate in tours, outings and events at the Mare Island Shoreline Heritage Preserve. Visit the Preserve open Friday through Sunday and holidays 10:00am-to one hour following sunset.

The Mare Island Shoreline Heritage Preserve is a 215-acre park located at the south end of Mare Island on land that formerly served as the U.S. Navy's first Naval Ammunition Depot, founded in 1857. Until we opened it for regularly scheduled access in April 2008, the land was off-limits to the public due to past sensitive Navy munitions production and storage operations and more recent environmental cleanup.

The property was granted by the California Legislature through the State Lands Commission to the City of Vallejo for development as a historic and nature focused park for all Californians in 2002. As an all volunteer group we are committed to providing for regular public use of the first phase of the regional park that includes the oldest naval cemetery in the Pacific, founded in 1858 and the 130 acres leading to the hilltop vista point. Access is through arrangements with the U.S. Navy and the City of Vallejo.

It takes a host of individuals, non-profit groups, agencies, local and regional businesses, corporations and foundations working together to realize the reuse of abandoned military property like this site as parkland.
