Group Events at the Waterpark

Groups of all shapes and sizes are welcome at Cascades Indoor Waterpark to warm up and take a dip! Our group visits have already accommodated: Family Reunions, School Field Trips, Boy Scouts, Fraternal Organizations, Residential Life Programs, Schools, Corporations, Not-for-Profits, Religious Organizations, and Sports Teams. You could be next!

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.


Consignment is one of our favorite promotions. We’ll give you ‘x’ number of tickets for your corporation, group, or Not-for-Profit. You can sell the tickets at our group rate as long as you promise to sell ‘y’ number of tickets. This program is a great ‘employee reward’ or ‘employee perk’ to offer your staff. It allows your team to access Cascades Indoor Waterpark on a Thursday or Sunday, with the buying power of your group.

Group Events at the Adventure Center

We’d love to lead your group on a great adventure! We work with amily reunions, school field trips, scout troops, residential life programs, schools, corporations, not-for-profits, religious organizations, sports teams and more! Special pricing applies for groups over 20 people!
