Vallejo, Calif.- When visiting San Francisco Bay Area, an often overlooked attraction that is affordable and entertaining at around $30 / person, includes both a marine park and thrills rides.

However, the Six Flags brand also includes extreme thrill rides that some people go to theme parks specifically to enjoy. With the combination of aquarium and ride park, this is one of California's most affordable adventures appealing to a variety of interests.

Dolphin Discovery allows guests to swim with the dolphins or become a trainer for a day. Tava, the African elephant, Jocko the walrus, and Shouka, the killer whale are a few of the stars at this amusement park. Odin, a rare white Bengal tiger loves to swim and you can watch Odin up close, or check out two Siberian tiger cubs born in April 2010, Maksim and Mischa, who are growing bigger day by day!

Six Flags Discovery Kingdom is open every day in June and July. Seasonal shows during the Christmas holiday and other times of year are offered, but summer provides the perfect weather to visit and enjoy San Francisco, Napa Wine Country and Vallejo's Six Flags. Many people aren't aware that the theme park has this major aquatic element to it well worth checking out, even if you aren't an extreme thrill ride seeker wanting to ride Tony Hawk's Big Spin, Tazmanian Devil, Voodoo, and Medusa, the first floorless coaster on the West Coast
