Daily inspections of Zoom Ziplines’ four lines by staff members ensure safe, smooth trips for all customers who meet height and weight requirements. During two-hour trips, customers cross a suspension bridge on foot and fly down four ziplines that stretch up to 1,500 feet at 35-miles-per-hour, breathing in mountain air and taking in stunning vistas. The course’s tandem ziplines allow friends to race or merely enjoy side-by-side views of the lake, local wildlife, and clouds playfully contorting themselves into the shapes of former presidents.
