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 and 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!

Maui Sands Resort

A Hawaiian themed resort, offers an arcade, two restaurants, and is more affordable than some of the bigger resorts in the area. However, this resort is not as infant/toddler friendly since you have to pay for anyone entering the waterpark.

Rainwater Park

Located down the street from Cedar Point, Rainwater Park has an indoor and outdoor waterpark, an arcade, laser tag, bowling, and miniature golf. However, the hotel is located directly behind the popular bar “The Thirsty Pony” which has the tendency to be very loud in the evening so if you plan to stay the night it might not be the best option for those with young children or light sleepers. Day pass packages are available.
