Sitting less than 20 miles south of Salt Lake City, this 1960s-themed water park is decorated with surfboards, sandcastles and a 1967 Volkswagen Beetle water feature. At the park’s elaborate water playground, kids have access to bridges and tunnels that span 12 levels, as well as 300-plus water toys and a 1,500-gallon dump bucket. While older children twist through the 1,000-foot-long Mondo waterslide in the dark, little ones can lounge at Cowabunga Beach or enjoy Cowabunga Kid’s Cove’s smaller slides.
