This course begins with a 20-foot high climbing wall that participants must scale to get on to the course, which rises as high as 30 feet over Zoo grounds. Along the way, riders will climb through an adventure net, negotiate a swinging, slatted bridge and walk between platforms on a series of logs, among other challenges. They’ll zip over the fence that encloses the main Zoo grounds, then must conquer a horizontal climbing wall between two aerial platforms before zipping back.
