This historic fort is on a site that had been fortified by the Spanish by 1794 and was used by the military for almost two centuries after that. Today, it’s a tourist magnet, but well worth a visit on clear days, when the views of the base of the Golden Gate Bridge are excellent. Though the usual views of the bridge are from above or afar, seeing it from the base gives you a new sense of just how astounding a construction it is.
Keep an eye out for harbor porpoises in the waters offshore (though the truth is that the best place to see porpoises is from the bridge itself, if you can stand looking down with binoculars! Check out our feature article all about the porpoises to learn more.)
