Since 1969, Big Surf has been the closest thing Valley residents have to a real beach, featuring everything from a wave machine to children crying about hot sand between their toes. The 2.5-million-gallon Waikiki Beach Wave Pool tends to be packed with older kids and adults astride rafts, boogie boards, and surf boards (all available for rental). Other park attractions make a splash with younger tykes, like Captain Cook's Landing (for toddlers), Bora Bora Bay, and smaller Otter Slides for kids under 4 feet tall. Adults can whet their appetite for water slides with seven different attractions, including The Black Hole enclosed slide and winding Tornado Twisters body slides — perfect for racing friends into the plunge pool below. You can even learn to surf here; lessons are available on designated weekends.
