The adventure Starts at AHA!

Young children together with you are invited to use imagination, creativity, and sense of discovery in the 8,000 square foot facility. With over 60 hands-on exhibits, children from 6 months to 8 years of age can become explorers, scientists, engineers, and artists.

The Raymond B. Martens Nature playscape is open year-round for you to discover Ohio’s natural beauty through all seasons. Drop in during the week for one of our many STEAM-centered programming activities or host your next birthday party with us on the weekend!

No matter the reason for your visit, you’re sure to have a one of a kind play experience at AHA!
