In this adventure, we traveled to Pigeon Forge, Tennessee to try Zorbing at the Outdoor Gravity Park (hint: this is the only Zorbing Park in the USA!). In zorbing, you dive into an 11 foot giant inflatable ball and roll.... well... down a 1,000 foot hill. Zorbing was invented in New Zealand. There are 3 different tracks to choose from and we tried all 3! This is a must if you are in Tennessee!
