A “Bavarian” Waterpark In Michigan Feels Like A European Getaway With Waterslides
Michigan has officially put Bavaria in a swimsuit, and the result is gloriously splashy.
This indoor waterpark opened in 2025 with cuckoo-clock chaos, alpine details, and enough slides to turn a cold-weather weekend upside down.
A dragon blows an alphorn. Goldfish wear tiny hats. Even the lazy river refuses to act lazy!
Sixteen waterslides, a wave pool, and a warm outdoor spa keep the energy high without making the whole place feel frantic.
Kids can chase the biggest thrills, while adults can claim a calmer corner.
Who needs a plane ticket when a little European weirdness comes with swim trunks?
A Grand New Bavarian Chapter
Big dreams usually start small, and this one began back in 1986. That was the year the Bavarian Inn Lodge first opened its doors in Frankenmuth.
The resort expanded repeatedly over the decades, adding rooms, pools, restaurants, games, and family attractions in a series of major phases.
The biggest expansion arrived with Bavarian Blast, which soft-opened on March 21, 2025.
The new development added about 170,000 square feet of waterpark and family entertainment space. That expansion made the complex the largest indoor waterpark and family fun center in Michigan.
The project added 16 new waterslides, a wave pool, a not-so-lazy river, toddler attractions, private cabanas, and a much larger Family Fun Center.
Frankenmuth’s German heritage gives the theming a natural home. The lodge had already leaned into European-inspired architecture and interiors long before the waterpark arrived.
Because the main waterpark is indoors, it operates throughout the year. Cold weather outside does not change the basic plan inside.
Bavarian Blast has its own entrance at 700 Weiss St in Frankenmuth, while the adjoining Bavarian Inn Lodge uses One Covered Bridge Lane.
Storybook Details Around Every Corner
Look down before you look up. Blue-and-white floor tiles echo the pattern associated with the Bavarian state flag. That detail is only the beginning.
Slides emerge from a giant cuckoo-clock structure, brightly colored Bavarian-style birdhouses appear throughout the space, and whimsical animal figures add movement around the water attractions.
One of the best visual jokes is Goldie’s Glider, a child-friendly ramp slide decorated with a goldfish wearing an alpine hat. The park’s themed characters keep the design playful without losing the German-inspired thread.
Cuckoo’s Chaos pushes the theme even further. Its tower resembles an oversized cuckoo clock, and water spills from beneath the bird above the play area instead of using a conventional tipping bucket.
Natural light changes the mood as much as the decorations. A large glass roof and glass walls brighten the interior during the day, helping the space feel open even in colder months.
The combination of practical flooring, oversized storybook structures, animal water features, and alpine details makes the waterpark feel more designed than decorated.
A slower lap through the building is worthwhile before the first ride. There is enough visual detail here to miss things when moving straight from slide to slide.
Sixteen Slides, Endless Choices
Sixteen new waterslides give families a wide range of choices, from gentle children’s slides to larger raft and racing attractions.
Super Duper Dragon’s Flight is one of the biggest shared rides. The blue-and-white raft slide carries groups through a high-energy course before returning them indoors.
Competitive riders can head for Schnitz & Fritz Racers, a side-by-side mat racing slide with a 42-inch minimum height. Rapunzel’s Racers offers another head-to-head option for guests who want a faster challenge.
Smaller riders are not left watching from the sidelines. Schmetterling’s Landing is a gentle butterfly-themed slide for children 36 inches and taller, while Kinder Blast and Sunny’s Slide provide more entry-level choices.
Cuckoo’s Chaos has four additional slides built into its play structure, including Bavarian Blitzer, Pretzel Twist, Buttered Noodle, and Schnitzel Swirl.
The park uses colored wristbands tied to height requirements. Children under 48 inches must wear a U.S. Coast Guard-approved life jacket, and each attraction has its own posted rules.
Checking those requirements before climbing the stairs makes it easier to choose attractions for different ages.
A River With Real Attitude
Lazy is not quite the right word for Greta’s River Run. The roughly 300-foot attraction moves riders through a stronger current than a traditional slow float.
The route winds through a themed garden setting with flowers, vegetable beds, a bird bath, and playful characters along the way. Water sprays add a few surprises without turning the ride into a full-throttle attraction.
The current is still gentle enough to work as a break between larger slides. That middle ground is the point: it offers movement without requiring the same energy as the racing and raft rides.
The river curves through the center of the waterpark, making it easy to watch the surrounding activity while floating.
Its storybook landscaping helps it stand out from a standard concrete channel. The garden theme also connects naturally with the cuckoo clocks, alpine colors, and animal figures used elsewhere.
For families splitting time between high-energy slides and calmer attractions, Greta’s River Run works well as a reset.
It is one of the clearest examples of how Bavarian Blast takes a familiar waterpark feature and gives it a more playful identity.
Waves Announced By A Dragon
Most wave pools use a simple signal. Here, a dragon with an alphorn announces what is coming.
The show is tied to Willy’s Waves, the large wave pool near the castle-themed backdrop. The dragon sounds the horn before the water system begins producing waves, turning a practical warning into part of the attraction.
The pool can create several wave patterns, ranging from gentler movement near the shoreline to larger waves farther out. One of the stronger settings is nicknamed the Big Kahuna.
A zero-depth entry gives the pool a beach-style edge, making the transition into the water gradual. Families can stay shallower while confident swimmers move farther into the pool.
The wave system gives Michigan families an indoor option that still feels a little like a beach day during colder weather.
Lifeguards are trained through the American Red Cross, and complimentary life jackets are available. Guests under 48 inches are required to wear an approved life jacket.
The dragon may get the attention, but the safety rules still matter once the waves begin.
Pint-Sized Splash Zones
Tiny swimmers get their own section at Puddle Platz.
The shallow activity pool ranges from zero to 18 inches deep and is intended for younger children and their supervising adults. Five small slides and low-depth play features keep the scale manageable.
Children 36 to 39 inches can use the Puddle Platz slides independently, while smaller children may use them with a supervising companion when they can walk independently.
The wristband system makes those limits easy to identify. Nearby, Cuckoo’s Chaos gives taller children a next step. Its four slides add more speed and variety without sending younger guests directly to the largest attractions.
The oversized cuckoo-clock tower anchors the whole play area visually. Water spills from the structure above, adding a big splash moment to a section already packed with smaller slides.
These two areas make the park easier for families with mixed ages. One child can stay with low-depth play while another moves into more active slides nearby.
That range matters in a waterpark this large because not every visit needs to revolve around the biggest ride in the building.
Warm Soaks Under Open Sky
Bavarian Springs offers a different pace from the slides.
The family spa connects indoor and outdoor sections, so guests can move through the water without ending the soak at the exterior wall. It remains available as a year-round attraction.
Warm water and open air create an especially noticeable contrast on a chilly Michigan day. The experience feels completely different from the wave pool or the faster slide complexes only a short walk away.
The indoor-outdoor design is useful for families who want a quieter stretch without leaving the waterpark. It also adds variety for visitors who have already spent hours climbing stairs and riding slides.
Elsewhere in the lodge, additional pools and whirlpools expand the quieter options beyond Bavarian Blast itself. One separate pool area is reserved for adults.
Staying hydrated and taking breaks between warm-water sessions and active attractions is a sensible approach during a full day.
The spa is not the loudest feature in the building, but that is exactly why it works. It gives the day a pause without requiring anyone to get dressed and leave the waterpark.
Dry Fun And Smart Tips
Wrinkly fingers do not have to end the day. The expanded Family Fun Center adds plenty to do away from the pools.
A three-story ropes course rises above the floor, and climbing walls add another height-based challenge.
Mini bowling, laser tag, indoor mini golf, and more than 180 arcade and redemption games round out the dry-side lineup.
The waterpark currently opens from 10 AM to 8 PM Sunday through Thursday and from 10 AM to 9 PM Friday and Saturday.
Day passes are available for visitors who are not staying overnight. Registered lodge guests receive waterpark wristbands as part of their stay, with access beginning at 4 PM on the check-in date.
Lockers come in several sizes. Guests are encouraged to bring their own towels, while towel rental is also available with a resort wristband.
Complimentary life jackets are available throughout the waterpark, and family changing rooms make it easier to manage younger swimmers.
Bavarian Blast is now a major part of Frankenmuth’s year-round appeal. The mix of slides, wave action, child-friendly play areas, warm-water spaces, and dry attractions gives Michigan families a getaway that can work in almost any season.
