Treasure Island revisited, a photo tour

There is something cool about visiting an island in the middle of San Francisco bay. Treasure Island has such a kitschy title that harkens back to something mysterious and full of surprises, considering it was named after the novel Treasure Island, by Robert Louis Stevenson who live briefly in the city. Entirely man-made from landfill, the island was originally planned as an airport for the popular Pan-American clipper planes, but instead it was used strategically to host the Golden Gate International Exposition in 1939-1940, and later became a naval base. Currently the island is used for rental housing, cinema studios for the large hangers, office rentals and special events.

Wow, the views are spectacular

On a clear day from Treasure Island, you can see gorgeous views around the bay from the hillside coastal ranges all the way through the Golden Gate Bridge and beyond to the Pacific ocean. In fact you get a 360 degree view of the entire Bay Area from here and adjoining Yerba Buena Island. Alcatraz island is just in front of you, with the Golden Gate bridge in the background, the Marin headlands and Sausalito is just to the right of the bridge. On the left of the bridge are expansive views of San Francisco’s skyline and bay front. Treasure Island connects to the Bay Bridge which directs traffic from San Francisco to the East bay cities of Oakland and Berkeley. A new extension bridge is being built on the Oakland side with a modern single suspension span that will bring the wow factor to Oakland and the general East Bay.
