Aquatica is a whimsical, one-of-a-kind waterpark that's only in Orlando and could only come from SeaWorld. There is one river where guests float through an undersea world of colorful fish and another that races into rolling rapids. There are also slides that spin and soak visitors, and Aquatica's incredible signature ride: two awesome, enclosed tube slides that speed through a lively lagoon filled with playful, black and white Commerson's dolphins. Operation hours vary by season.
