Six Flags Discovery Kingdom is the only combination wildlife park, theme park and oceanarium in the world. Previously known as Six Flags Marine World, this re-branded 136-acre theme park features more than 50 rides, shows and animal attractions in three themed areas.
It began as a nonprofit animal park Marine World in Redwood City, California in 1968. In 1985 the park relocated about 55 miles away to Vallejo, California and thought the move necessitated a name change to Marine World Africa USA. The old location became known as Redwood Shores.
In 1999, Marine World was re-branded and re-named Six Flags Marine World.
In 2007, the park was again renamed Six Flags Discovery Kingdom to better represent the offerings at the park.
