Grand Splash® Waterpark is an oasis for young and young-at-heart guests. Enjoy an intimate gathering in our jumbo hot tub by the waterfall or a giggly visit with grandkids who love our Lily the Frog slide. Families with teenagers get a thrill when using the 98ft high body slide that circles out of the building and quickly shoots them into the Grand Splash® pool. If you are looking for some quiet exercise, use pool during the adult only time. The Grand Splash® Waterpark has private rental rooms available that are inches away from the pool. These rooms make the perfect space for party hosting. Contact our Front Desk today to inquire about reserving your special space right inside the waterpark 218-326-2600. Please be aware that the 98-foot slide does not operate Monday through Thursday from Labor Day to the 1st week of June; during summer months it is open 7 days a week.
