About this activity

Are you ready to make a SPLASH on your next family day out? Just head to The Reef Indoor Water Park in Billings, because there is something pretty special about it. Do you know what it is?

Well, it's actually the LARGEST indoor water park in the entire state of Montana - in fact, it's as big as a football field! We hope you are ready to be impressed!

The Reef is where kids can climb three stories up, then blast down the Barracuda Blaster, or take on the Tropical Twister, before you shoot into the plunge pool below!

The Reef is where you can ride the 3ft waves in the 55,000 gallon wave pool, and imagine you are out in the big, blue ocean! If you want to relax a little, how about taking a dip in the 20 person hot tub where the water is always 102 degrees?

Perfect for when that Montana weather isn't going to plan!

You can also try something new at The Reef - every heard of water basketball? Why not give it a go - you might be an expert at it!

For those little ones in the family, The Reef has them covered too. They have an interactive playhouse designed JUST for them, with tunnels, squirt guns, slide, mini tubes, and yes - a dumping bucket - watch out!

With tables, family space, and a cafe, there is plenty to give you that COOL family day out in Montana - so let's make that splash!
