Treasure Island is a beautiful man-made escape in the San Francisco Bay, between San Francisco and Oakland. Sea lions can be observed in the water from the shoreline, and construction of the new eastern span of the San Francisco Oakland Bay Bridge can be observed from the eastern part of the island. Here, Treasure Island has taken advantage of this gorgeous location to make it San Francisco's ultimate party and celebration destination. Surrounded by majestic Bay Area views, Treasure Island offers three rooms and a spacious outdoor area for your wedding, New Years Eve celebration, birthday party, romantic night out, or any other special party events.
Treasure Island is entirely within the City and County of San Francisco, whose territory extends far into San Francisco Bay and includes a tip of Alameda Island.
