You have a best-of-both kind of situation here: on the one hand, you have the endless acreage of the Presidio Park, and on the other, all the sights of San Francisco. The building itself has plenty of book-reading and board-game-playing potential, or you can wander around the grounds admiring the architecture. Hiking is the unofficial state pastime of California and here it comes with a side order of Golden Gate Bridge views: the Presidio has various trails, which you can walk, cycle and jog along. The Presidio Officers’ Club, which was inaugurated in 1776, is now the park’s official, free-to-enter museum – and, if you’re not a museum kinda guy, just go for the Mexican food. Crissy Field Beach is the perfect destination if you like your swims, cycles and seafront strolls to overlook that awesome feat of 1930s architecture, the Golden Gate. Marshall’s Beach gets you even closer.
