San Francisco, CA
Play: Humans soak up iconic views of the Golden Gate Bridge and the San Francisco skyline while dogs romp on a sandy beach and splash in the bay at Crissy Field. There’s an adjacent grassy area with picnic tables (leash required), and the Warming Hut has lattes and snacks. The Golden Gate National Recreation Area is proposing new on- and off-leash restrictions, but for now the doggie coast is clear. parksconservancy.org.
