Mack Indoor Pool is the City of Ann Arbor’s only indoor public pool and offers a variety of programs and opportunities for every swimmer. Our six-lane, 25-yard main pool has an attached 30-by 42-foot children’s tot pool. A ramp leading into the pool provides for easy accessibility. Our heated indoor pool allows you to swim, even if the weather is not “summer like.” Sign up online for our lessons or programs using our online registration system. ​​
