Celebrate the last blast of summer with an evening just for members! Join us for exclusive access to the Wonderground. Climb, explore, and enjoy one more carefree summer evening before school and fall routines begin.

We’ll provide popsicles and cold drinks while supplies last—just bring your family and get ready to play. It’s the perfect chance to make a few more summer memories with your favorite museum crew!

Free for all members!

Please enter and exit through the Wonderground gate on Dayton Street behind the museum! The building will be closed for this event.
