Don't leave your heart in San Francisco. Head north, and take it to San Rafael instead. The biggest city in Marin County, it still maintains the groovy charm of a small town on the Bay. One of the sunniest cities on our list, San Rafael offers plenty of outdoor activities for the social set.
Hit downtown for year-round concerts, markets and events. Nature lovers can canoodle in the 1,600-acre China Camp State Park. And if you're looking for a truly laid back way to meet people, join a league and roll some balls at the Marin Bocce Federation.
