Visit Tips
Treehouse Time is not a full-day free-for-all, so check the calendar and register in advance.This is a strong option for kids who enjoy movement-based play but do not need a huge action-park scale.
Family FlowBecause the schedule includes classes and camps, open-gym access is best treated as a choose-your-session visit.

About the Venue

Treehouse Gymnastics is a non-competitive gymnastics and play gym in Lebanon that does a nice job balancing structured programming with family open-gym time. For indoor-play families, the biggest draw is Treehouse Time: a pre-registered free-play session with inflatable slides, trampolines, and gym equipment that feels more welcoming and less intense than a hardcore training gym.
