💬 What Parents Say
- Visit during evening special hours (5-8pm) for the best value - the entire family can enter for just $18, making it significantly cheaper than daytime rates and comparable parks in the region.
- Don't miss the zipline - it's the only aqua zipline in Iowa and consistently highlighted as a must-try attraction that sets this park apart from larger competitors.
- Plan to spend time in both the outdoor and indoor sections. Outdoor features three waterslides, diving boards, and a water-climbing wall, while the indoor portion has a lap pool, obstacle course, and additional slides.
- Bring young children during designated family hours - the park has a dedicated children's play area with a small slide, shallow kids' pool, and lazy river suitable for all ages.
- Check the activity registration calendar (asc.activityreg.com) for winter hours before visiting, and note that waterpark rentals are available Wednesdays and Saturdays 6:15-8:15pm if planning a group event.
