There is no access to Point Bonita Lighthouse when closed as the final leg of the trail to the bridge and lighthouse passes though a rock tunnel which is gated and locked outside of opening hours.
Point Bonita Lighthouse is normally open only on Sunday and Monday from 12:30 pm to 3:30 pm.
The short, steep trail from the car park as far as the tunnel gate remains open daily, and offers good vantage points with views from the Marin Headlands towards the Golden Gate Bridge.
