Attractions and tips

No trip to San Francisco is complete without gazing upon the Golden Gate Bridge, a 1.7-mile span that is walkable and is considered one of the 7 Wonders of the Modern World. Alcatraz Island was a federal prison from 1934 through 1963 and housed Al Capone and Machine Gun Kelly.

Pier 39 is famous for its seafood and clam chowder, and it’s equally well-known views of the city and the bay. The Presidio is a national park site, which was once a military post, and now features recreational activities along with historic and architectural treasures. The Yerba Buena Gardens feature museums, public art, a children’s garden and an historic carousel.

San Francisco has relatively dry and warm - not hot - summers and mild winters, but its climate can be very unpredictable due to its proximity to the Pacific Ocean, San Francisco Bay and the Sierra Nevada Mountains coastal range. Expect a chilly, damp fog during May and June mornings and persistent overcast skies until afternoon.
