its most famous feature is perhaps the Golden Gate Bridge.
Completed in 1937, this is a really beautiful bridge to bike or walk over, or just view from your car. One place nearby for a great view of the bridge is the lively Presidio. it's also a good place to spend time outdoors on a sunny day. Go windsurfing,jogging. or just sit and relax. The Palace of Fine Arts is worth a visit, too.
