4) Crissy Field, San Francisco
Sitting pretty at the edge of San Francisco Bay with a stunning view of the Golden Gate Bridge, few beaches can compete with Crissy Field’s distinctive location. More popular with San Franciscans who want to get out of the city and take a break from those thigh-burning hills than with visitors from out of town, Crissy Field is a combination beach, wetland and picnic space where you can splash in the sea, sunbathe, cycle, run or just sit back and enjoy the fresh air. The winds that blow through the Golden Gate Bridge and along the beach make it an ideal spot for kite-surfing and its off-leash policy make it a great place to bring the family pooch.
