San Francisco is a diverse city that often finds itself on the edge of social and technological change. The small city has long been a haven for marginalized groups, but it is also a place that is grappling with its identity in the throes of a tech boom. To really know San Francisco, you must explore its neighborhoods. Look for taquerias and techies in the Mission, rainbow flags flying above the Castro, earnest hippie vibes in the Haight, and beachy quietude in the Sunset. Visitors will find the city welcoming and full of activities for nature lovers, bookworms, shoppers, foodies, cultural mavens, and more.
