Rules & Restrictions
- Open gym is held in 2-hour sessions on weekends and weekdays. You can find all dates and times on the link above.
- Cleaning of obstacles and common areas is conducted regularly
- Regular open gym is for kids and adults ages 5+. This rule is for the safety of all our guests! Especially when the gym is busy and crowded, it is easy for the younger children to wander and get hurt.
- Also, all of our obstacles were built with that age in mind, so there is not much for smaller and younger children to do.
- Younger children are allowed in the building to watch – please keep them in the viewing area and off of the obstacles.
- Sneakers are REQUIRED to play on the obstacles. NO socks, boots, or flip flops allowed.
- Your first visit we require everyone goes through our intake process – a staff member will show you around the gym, go over all rules, show you some obstacles, and go over where you can and cannot go in the gym.
- A waiver is required from every participant
- There is always staff on the floor to watch for safety, give tips, and cheer you on.
- Don’t be afraid to ask questions – we are here to help!
