Yes, the Los Angeles area is home to several major water parks, though most are located in the surrounding suburbs of LA County. The most famous is Six Flags Hurricane Harbor, a 22-acre park located in Santa Clarita, adjacent to Six Flags Magic Mountain. It features over 23 slides and a massive wave pool. Another legendary park is Raging Waters Los Angeles in San Dimas, which is California’s largest water park and contains 50 different attractions, including the "Aqua Rocket," a hydromagnetic water coaster. For a more "neighborhood" feel, DryTown Water Park in Palmdale and Splash! La Mirada Regional Aquatic Center offer great family-oriented splash zones. If you are staying in Orange County near the Anaheim area, Knott's Soak City and the indoor Great Wolf Lodge are popular year-round choices.
