Obscura Society SF: Fort Baker Waterfront and Bunker Walk

Join historian John Martini for a walk around the former home of big guns defending the bay

Fort Baker today is the home of the trendy Lodge at Cavallo Point, but in the 19th century it was the home of Coast Artillery gun positions that defended San Francisco Bay. On this tour at Fort Baker we’ll walk past the renovated barracks and officers’ quarters lining the fort’s parade ground, then proceed along the waterfront where the “army’s navy” was moored during World War II. Next, an uphill climb to the former gun emplacement of Battery Yates with its spectacular views of the Golden Gate Bridge. By special permission, we’ll then go into the long-closed earthen fortification at Battery Cavallo to explore its 1870s brick tunnels, including a passageway to a lonely observation post overlooking Angel Island and Alcatraz that few people have ever seen.

Our guide is retired National Parks Ranger, historian, historical preservationist, author and lecturer John A. Martini. Mr. Martini is a 4th generation San Franciscan and has worked across the American West but his professional focus is primarily on this incredible city we call home.
