Flying Squirrel, Zelienople

With sprawling locations across the US and Canada, Flying Squirrel stakes a claim as the largest indoor trampoline park in the world, inviting guests to defy gravity on multiple courts of interconnected trampolines. Beyond simply bouncing, jumpers can practice acrobatics at the freestyle court, channel NBA all-stars by slam-dunking on basketball hoops, and practice mid-air evasive maneuvers at the dodgeball court. Off-trampoline attractions include a foam pit with rope swing, fidget ladder, Ninja course, laser maze, and cafe, all of which come in handy during private parties. "Air traffic controllers" monitor activity throughout the facility—particularly on the kiddie court—to ensure jumpers' safety and tell them when to stow their landing gear.
