Cincinnati's best kept secret. We almost didn't go because I couldn't find much about this but decided to give it a try. This is in the basement of the city museum at the old train station. It's dim but amazing and much bigger than you think! The museum has it all plus a ton of room to play! Best for ages 1-10 and we were impressed with the space for toddlers and babies! There is a nursing room for moms, clean bathrooms and a place to eat upstairs. The water room was a hit! There is also a huge treehouse and educational sections to learn about children from different cultures. We could have stayed all day!!
