Huge gym space that hosts 'open gym' times!
This huge gymnastics facility offers classes for aspiring gymnasts, but they also open up their facility at various times for 'open gym', so those of us that just want to jump in the foam pit. In the summer, the open gym times are usually daily (check their website.) If you are visiting AZ in the summer, you might be looking for something indoors to do besides going to a movie. Kids are $7.50 for open gym of 2 hours. 18 months and younger are free and parents are free. They have staff out to help the kids and monitor the chaos, but it's basically free time. My boys love jumping on the trampoline and swinging from the rings. I love that they are worn out after a solid 2 hours of exercise! I also like, that parents aren't just sitting on the sidelines, but involved in the gym with their kids.
