Splash pads in Westerville, Ohio

Blendon Woods is one of Columbus Metro Parks' nature-first spots, and the splash feature near the nature center keeps things woodsy and chill. Ground jets on a small fenced rubber-mat deck — toddler-perfect, with mature shade. Free parking at the nature center, clean restrooms, and the bird-watching boardwalk a short walk away keeps grandparents happy. Central Ohio humidity gets thick in July but the tree canopy here is the real win. Pair with the lakeside walk or a stop at Jeni's Splendid Ice Cream in nearby Easton. Open roughly Memorial Day through Labor Day, daytime hours; closes early on event days.

Westerville Community Center's splash area is the all-weather indoor-outdoor option for the Columbus northern suburbs. Outdoor ground jets and a couple of taller features on a fenced rubber-mat deck, with the indoor aquatic center as a rainy-day backup. There's a fee for non-residents but it includes pool access, which is the deal — this is a half-day stop, not a quick cool-off. Free parking, locker rooms, snack bar. Central Ohio humidity is real but the indoor option means rain or shine you're covered. Pair with dinner on Westerville's Uptown strip. Open year-round indoors; outdoor splash Memorial Day through Labor Day.
