~UPDATE: CLOSED~
GymTastics is a gymnastics center. Their main focus is lessons, but they also offer open gym times which are available to the public. My kiddo enjoyed her lessons, but she really loves just going to play as well.
Her favorites are the trampolines and the foam pit! Not a bad way to burn off some energy for a couple of hours!
Open gym is only at certain times, so be sure to check the schedule online or call to check before heading over there.
