There are just under three miles of pathways that are available for pedestrians and bicyclists to explore the shoreline and inland areas of the park. These pathways are extensions of the regional San Francisco Bay Trail, and connect directly to the adjacent Port View Park and the West Oakland neighborhood.
From San Francisco: Take I-80 east (Bay Bridge/Oakland) to I-880 south toward Alameda/Airport/San Jose. Exit onto West Grand Ave./Maritime Street. Continue straight, then turn right onto Maritime Street. At the BART tracks, turn right onto 7th Street. Continue straight on 7th Street to the stoplight at Middle Harbor Road. Proceed through the intersection and take the first right turn into the MHSP parking lot.
