Great tour! You have to stand outside and keep a sharp eye out but we saw dolphins, sea lions, pelicans, cormorants, gulls, and many other sea birds. The operators spent plenty of time in the photo op locations and had short and sweet informational blurbs about the high points. Great views of Alcatraz Island, Sausalito, and the Golden Gate Bridge. Listen to me when I tell you it is WINDY!!! Bring appropriate layers.
