Sun Splash Family Waterpark is Southwest Florida's largest waterpark. At the Sun Splash Family Waterpark in Cape Coral, you can test your nerves on the Electric Slide, a Kelly green five-story twisting tube slide, or you can relax and catch some rays on the Lazy River. Other attractions include Cape Fear and cable drops. There are water playgrounds for kids, and volleyball and video games for non-swimmers. Have lunch at the Calypso Cafe. The park is open from mid-March to mid-October.
