Inside this massive North Carolina waterpark, the day quickly fills with splashing, laughter, and at least one person insisting they are “not getting soaked” moments before getting completely drenched. Make Carolina Harbor The Daytime Splash ZoneFamilies with different ages and comfort levels can find more than one way to enjoy the waterpark. Carolina Harbor is officially described as a 26-acre waterpark, correcting the 27-acre figure that appears in some older descriptions. That approach keeps the glow-night promise truthful without tying it to expired fireworks or water attractions that have already closed. Carolina Harbor provides the daytime escape, and the wider Carowinds property supplies the glowing finish once summer darkness begins settling over the park.
