We had a blast celebrating our sons birthday here! The avalanche did not go off once on this trip, though. Usually, it pours down; we spent the entire day and were a bit disappointed that it didn't happen. Of course, they all had a great time anyway. We had cheese bread and pizza for lunch, and both were good.

Had a great time. Highly recommended for adults and families. Plenty to do. They say that you can't take outside food or drink in, but it's unregulated and pretty easy to take in snacks and water bottles within reason.

We went on a Saturday evening and it wasn't super crowded, things were open and working well... it was just so cold. You walk in and think it's going to be fine, but once you get wet you're freezing. Our 1.5 year old son's lips turned blue and was shivering within minutes of being in the toddler area, we had to take frequent trips to the (crowded) hot tub just to warm him up. Kids are running from activity to activity with their arms crossed to keep warm and parents are sitting comfortably in chairs in their winter clothes. For the price they charge kids should be able to play in the water and explore the water park without freezing to death.

This place was way over crowded. Not enough room for even 1/3 of the guest to sit at anything. Every hottub full, pool and slide full. They tried to say their maximum capacity was 1000 which they do not have posted anywhere and if you look at capacity standards is more than. Double a reasonable state ordinance. The swimmer to lifeguard ratio also far exceeds safety limits. When brought to the managers attention she said it is always like this during the holidays and in 17 years they never had a problem. That doesn’t make it safe.

I’ve heard this is currently the largest indoor waterpark in Michigan. To me if felt the same as Zehnder’s Splash Village in Frankenmunth, however Avalanche Bay feels managed more efficiently and uses space better. I think they both have the same count of slides. The changing rooms here were much better and more spacious compared to Zhenders. The key difference to me is that you don’t have to wait as long for anything. Hands down the infrastructure is just better. Zhender’s has more people that go, I assume because of its proximity to the Detroit metro area. We visited Avalanche Bay during Michigan’s mid-winter break and I think the 3.5hr drive was worth it. Wishin the first hour alone we experienced more attractions than all day a Zhender’s. Two things really stood out to me and they were the surf current and kids/adult play structure. The surf current was so much fun and the staff was very helpful. The play structure with 2 slides was a lot of fun. Everything is adult friendly too as the slides were rapid and the water was warm. A small warning, this is the wettest play structure I have ever been too. So much water is squirting or falling from somewhere. Whereas places like Zhender’s you can safely navigate with your kids with getting only marginally wet. In short it is a lot of fun. I highly recommend this place as the quality is high and the property has many other offerings.
