Grab your comfiest sneakers and wander Crissy Field’s sandy trail—it’s basically a front-row seat to the Golden Gate Bridge, plus free ocean aromatherapy. Plop down on the lawn with snacks (or that pastry you “accidentally” picked up earlier) and watch kite-surfers and happy pups do their thing. Stick around for sunset, when the sky turns cotton-candy pink over Fort Point and your camera roll thanks you.
