They have a few open gym options, here they are:
The preschool open gym description isn't real clear- it's the last Saturday of every month at noon. So it's only once a month and it's $6 per child. My daughter had a blast! She got to play on the balance beams, bars, vault, trampoline, foam pit, rope, floor, and other random pieces of equipment.
I was very impressed with the instructor. Too bad they are so far away from us!
