An outstanding experience! Excellent hot summer day activity. The giant balls are a ball inside of a ball. You sign up and pay at the bottom of the hill, then They bus you to the top in groups. They load you into the ball through a double zippered hole after placing between 5 and 10 gallons of water inside. So wear clothing you don't mind getting wet. Upon entering the inner ball, you lie down in the water which is only deep enough to wet your back half. Refreshing on a hot day! They press record and hand you a waterproof GoPro video camera to record your ride. They double zipper the entry closed to keep you and the water inside.You have a choice of three courses for the ball to take from top to bottom. They roll you past the gate and your exhilarating ride begins! At the bottom of the hill they unzip and help you exit after taking the video camera and turning it off. Once out, they hand the video camera back to you to turn in at the video counter inside. You can buy your video which they place on a thumb drive so you can put it on your computer or upload to Faceboom or Instagram. I enjoyed the snot out of my ride! Leave valuables locked in your vehicle. Bring a towel and a dry change of clothes if you plan to attend other events or attractions afterwards. You can change in their bathrooms at the bottom of the hill. Go try it. You are sure to have a blast! About 3 or 4 tenths of a mile up Sugar Hollow Road behind the Cracker Barrel at Stop Light 1 in Pigeon Forge. A sure-fire summer hit!!
