I can’t think of anything that brings more joy to my children’s faces when it’s the dead of winter or a rainy spring day than when I tell them to go grab their swimsuit and pajamas because we are headed to an indoor water park for the night. Whether you are looking for a fun overnight getaway or want to spend the day splashing in the water, there are so many great indoor water parks in Ohio to choose from.

So grab your towels and goggles as we explore the thrills, slides and best lazy rivers that Ohio has to offer! With so many locations to choose from, there is sure to be one (or more) that is perfect for your family!

As usual, if you know of any other Indoor Water Parks in Ohio that should be included in this list, submit the details here and we'll get them added. Thanks!
