Spending Spring Break in April in Montana you never know what you're going to get. We were welcomed with snow and freezing temps :) My 9-year old son saw an ad for The Reef at the Billings airport so this was his idea (kudos to marketing!). We went on a Sunday and had a great time. For Billings this is... More

The slides are great, the wave pool in entertaining, and the water features provide some great physical challenges. We saw no equipment problems during our visit and the pool area seemed clean. Other guests brought picnic lunches (that seemed odd at an indoor park, but I guess it is normal at an outdoor park). The best thing about the park... More

I initially intended to stay at the Big Horn and spend time with my children at the Reef. I accidentally booked the wrong hotel (Billings Hotel), so because of issues with Big Horn (see review written there), I stopped by the Reef on my way out of town to get pricing information to plan my next trip. When I got... More

We took our 8 year old son and a friend to the waterpark. They had a blast..... even I enjoyed the waterslides. Not too crowded, clean, friendly staff.

nice rooms little high on price as it didn't inclued adissom to water park, 10.00 more per person so 40 dollars a day more other wise very good

For the same price almost as a movie, you can ride the slides and younger kids can ride on smaller slides! The kids play area has a big bucket that dumps water on them, slides, water cannons, etc. There are activity pools where you have to get across on Lilly pads or can shoot hoops. They have a wave pool,... More

Our party consisted of 2 adults, one of which was disabled, and 3 children and one baby. The only room available to us was a disability room with a king size bed and a sofa bed. The room was very small. As soon as we checked in the kids wanted to watch tv before going to the water park. The... More

Yet once again we paid a ridiculous amount of money to take our son to the indoor water park. Once again, he couldn't use all the slides, and for a first, we were thrown out of the hot tub as we sat in there WITH him and rudely told that next time make sure he was 48" before trying to... More

This water park had a little bit for all ages. 2 big water slides ... one you could either go down in single or double tubes. The other was enclosed all the way ... aka dark inside the slide. And it was cool that although enclosed, the slides went outside the building for a little bit. They had a hot... More
