Overnight Parties
That’s right – we want you to stay up all night at Cascades Waterpark and the Adventure Center. The Waterpark would be open exclusively to your group for an all-night party. We have already served and built custom programs for Youth Ministry Overnights, Project Graduations, Collegiate Residential Life Programs, and High School After Prom Parties.

We offer a fundraising program for groups that are looking to have a great time and make a little money while doing it! The minimum group size is 100, and the maximum is 300. No more long drawn out fundraisers where you have to collect and distribute items. Have your group schedule a date to enjoy the Waterpark and earn money from each ticket sold. Sell the tickets in advance and promote your event.

We offer excellent opportunities for Corporate and Private sponsorship of our Waterpark. Benefits include vacation ownership, signage in the Waterpark, exclusive corporate pool party, resort customer account, and much more.
