Six Flags Discovery Kingdom is a one-stop shop for fun and furry friends. In addition to roller coasters, Looney Tunes Seaport features pint-sized rides and character appearances, great for smaller kids. The animal area showcases big cats, reptiles, and sharks, among other creatures. Slow down in the butterfly habitat, and stick around for one of the many animal presentations throughout the day—think ball-balancing sea lions and jumping dolphins.
With a Go San Francisco card, you can combine your Six Flags Discovery Kingdom trip with other adventures around the city, including hop-on hop-off bus tours, Aquarium of the Bay, and the California Academy of Sciences. The pass includes entry to many attractions throughout the area, as well as jump-the-line passes at select sites. There are different pass options.
