Coastal trail along San Pablo Bay on historic Mare Island — shoot tidal marshes, shorebirds, industrial shipyard remnants, and wide bay panoramas at sunrise/sunset. Flat, easy trails and several shoreline pullouts; parking available near trailheads in Vallejo. No fee, but check signage for restricted zones around active facilities. Best light: golden hour for warm reflections; low tide reveals mudflats and bird activity. Expect wind and cool temperatures year-round.
