The Embarcadero is a long meandering stretch of road that covers from AT&T Park to Pier 39. Although the 1989 Loma Prieta Earthquake hit the Bay Area, one positive outcome was the release of the waterfront from the ugly shadow of the Embarcadero Freeway, which was damaged and then decidedly taken down.
The renewal of this area has been astonishing and has added immeasurably to the beauty of the city. In the past 3 years, an extension to the Municipal Railway lines has brought street car service (F-line) to the entire Embarcadero as far as Fisherman's Wharf.
The Ferry Building, the lauching point for both day 1 and day 2 San Francisco City Tours sits atop of The Embarcadero.
Pier 23, a great place for drinks by the bay is off of The Embarcadero too. There are walking tours on this famous San Francisco street, where one can see AT&T Park, The Ferry Building, Pier 23, Levi's Center, Bay Street Cruise Ship Terminals, Pier 39 and into Fisherman's Wharf.
