Point Bonita Lighthouse is out on the rocky point on the north side of the entrance to San Francisco Bay.The light is still actively used to warn approaching ships, but during the day the anyone can visit and walk around the outside of it. The lighthouse is accessible to the public during limited hours on Sundays and Mondays, as well as on ranger-led interpretive sunset hikes, which requires a sign-up. Access to the bridge is barred at other times by a metal door on the shore end of the tunnel.
