Bay seniors, and everybody else who is not actively serving in the US Coast Guard, are missing the awesome view from Yerba Buena Lighthouse in the middle of SF Bay. Built in 1875 in an octagonal Victorian style, it was automated in 1958. The keeper’s house is now occupied by a Coast Guard admiral. Directly facing downtown SF and surrounded by rugged gardens, it us unfortunately strictly off limits to us, the taxpayers who support it. Can’t imagine why.You can best see it sailing by and the best water tours seem to be arranged by the US Lighthouse Society. The oldest operational Bay lighthouse is the one on Alcatraz, badly damaged by the ’06 earthquake. You might want to check out the rare and scary tours of it, arranged by the Golden Gate National Parks Conservancy.
