Outdoor Gravity Park

Outdoor Gravity Park is home to one of the strangest and most memorable experiences available in the Smokies: you climb inside a large transparent inflatable sphere and roll down a Tennessee hillside. That's it. That's the activity. And it is absolutely, genuinely fantastic.

OGO balls come in two versions. The aqua version fills partway with water before you're buckled in, creating a sloshing, laughing, slightly chaotic tumble down the hill that kids come out of absolutely soaked and immediately asking to go again. The dry version is faster, more intense, and better suited to older kids who want the full disorientation without the water component.

The Pigeon Forge location benefits from a proper hillside with enough slope to generate real speed and a beautiful mountain backdrop. The ride lasts about 30-45 seconds inside the ball — which sounds short but contains approximately 200% of a normal child's daily excitement allotment. The footage, if you mount a camera, looks genuinely incredible from inside the ball.

This is not for young kids. A 7-year-old at the bottom of the height/weight range is probably fine with a reassuring parent. Kids under 6-7 should skip this one. Tweens and teens are the core audience — 10-15 year olds tend to be the most enthusiastic riders and will want to do multiple runs if budget allows.

Reservations are strongly recommended for summer weekends. The facility has limited daily capacity and walk-up availability disappears fast in peak season. Book online the night before at minimum.
