Avalanche Bay Indoor Waterpark

Avalanche Bay – the Boyne Mountain Water Park

At 88,000 square feet, Avalanche Bay indoor waterpark is Michigan’s largest.

Located at Boyne Mountain Resort (about 15 minutes off of I-75 in Boyne Falls in Northern Michigan), Avalanche Bay visitors have no shortage of options for fun, indoors and out, on their massive property.

A variety of fast waterslides – one includes a trap door! – and a surf simulator set the Avalanche Bay waterpark apart from others in Michigan. It’s a destination thrilling enough for teens, tweens and adults.

Attractions at Avalanche Bay Indoor Waterpark

Splasherhorn Mountain

Splasherhorn, in the center of the waterpark, it probably what you’ll notice first when entering the facility.
It is also where you go to get soaked when the 800-gallon mountain-turned-play structure erupts with water!


Climb bridges, play with sprayers, and whisk down the kid-appropriate medium-sized waterslides.

BONUS: Adults can ride these slides with little kids on their laps.

And yes, there’s even a pool area for toddlers and other little kids.

The little kid play area is next to the hot tub and features a zero-depth entry. It only gets 2 feet deep, making this a great destination for a visit with babies and toddlers.

Seven Different Waterslides

Vertigo Cannonbowl • My kids call this slide the “Toilet Bowl” and it is one of their favorites because it’s thrilling but not as scary as The Big Couloir Slide.

On this waterslide, carry your tube (singles or doubles) up to the top and then ride down, plunging into the bowl for a spin around the inside. For riders 48″ and taller. Mild thrill slide.

Downhill Mat Racer • Grab a mat, lay down face-first, and choose from one of four lanes to race your friends down the slide.

Each lane is a little different so you can change up your experience each time you go down.

There’s no height limit but life jackets are encouraged for small children.

The Big Couloir Slide • Just how brave are you?

Step into the launch capsule and wait for the trap door to open, dropping you almost straight down into a narrow tunnel, launching you into the 360° Super LOOP.

For riders 48″ and taller. Extreme thrill slide.

Rip Zone Surf Simulator

You can go indoor surfing on this indoor surf simulator at Avalanche Bay indoor waterpark! Boards are provided.
Best for tweens and older. Riders must be as tall as the boogie board to surf on the Rip Zone Surf Simulator.
