Outdoor Gravity Park is home to the iconic New Zealand zorbing adventure, OGO, where fun lovers slip, slide and get wet. An 11-foot transparent sphere sits perched at the top of a 1,000-foot hill. In a moment, its 300 square feet of plastic will go rolling towards the bottom—but only after a couple of things happen. First, up to three people dive into the sphere's belly. Then some of Outdoor Gravity Park's attendants toss 10 gallons of heated water into this signature attraction, and finally close the door on what's known as the OGO. The H2O makes for a slippery ride, though one without tumbling. The fast and adrenaline-packed descent is more akin to a bouncy water slide. Also new this season is a zig zag track called the FUNnel, offering a new spin on zorbing. Come join in the fun as the park is open rain or shine all year and bring a swimsuit and towel.
