San Francisco is a major city in California, the centerpiece of the Bay Area, well-known for its liberal community, hilly terrain, Victorian architecture, scenic beauty, summer fog, and great ethnic and cultural diversity. Each district of San Francisco carries its own unique and distinct culture. The Golden Gate Bridge is the well-known symbol of the city. Fisherman's Wharf is a touristy waterfront with Pier 39, Ghirardelli Square and the ferry launch to Alcatraz. Nob Hill-Russian Hill is a ritzy neighborhood with upscale hotels, cable cars, panoramic views and steep inclines. Chinatown-North Beach are vibrant immigrant communities; stylish laid back 'Little Italy' next to the crowded and largest Chinatown outside of Asia.
