Michigan's largest indoor water park is coming to Frankenmuth

Frankenmuth is known for its year-round holiday festivities, but it will soon also be known for having the state's largest indoor water park.

140,000 square feet of fun

Frankenmuth's Bavarian Inn Lodge is one of the biggest Bavarian-themed resorts in the U.S. Its new $80-million expansion will add over 100,000 square feet to its indoor water park and family entertainment center.

In an announcement from the Bavarian Inn Lodge, President Michael Keller Zehnder said the new project will create "unique attractions and new types of experiences, within our resort, for all ages." With over 20 new attractions, the latest expansion will put the Bavarian Inn Lodge at more than 140,000 square feet of family fun once construction is done.

The Lodge's largest expansion yet

This will be the Bavarian Inn Lodge's seventh major expansion since it opened in 1986. Some of the amenities included in the $80-million expansion are:

  • A large indoor wave pool

  • An adult-only swim-up bar

  • A series of water slides

"We're excited to announce more on the unique attractions that we're adding as the construction process is underway," Zehnder said.

Previously, the largest expansion the lodge saw was $14-million during its third phase in 1995 — when 156 guest rooms, a gift shop, third indoor pool, second restaurant and an 18-hole indoor mini-golf course were added.

All expansion phases of the lodge have been built by R.C. Hendrick & Son, Inc.

When will the new amenities be available to the public?

The construction process will kick off with a groundbreaking ceremony on Dec. 13 at 10 a.m. Various Zehnder family members and representatives from the municipality will address attendees during the ceremony, Zehnder said.

Certain new areas of the family fun center will be open late fall 2023, but guests will be able to fully enjoy the new attractions by spring 2024.

Operating with no disruptions

"The addition will not inhibit any of our guests from enjoying our four pools, three whirlpools and two water slides — or the 30,000 square feet of family fun center space with our indoor miniature golf, lots of video games and redemption games and arcade games," Zehnder said. "All of the areas of the existing fun center, and throughout the lodge, will be open for business as normal."
