A zip line consists of a cable or series of cables mounted onto anchor points on either end of the cable that allow movement from one end to the other. They have been around a long time, sometimes used instead of bridges in remote mountain areas or to move supplies from one side of a river to the other. Zip line participants attach their harness to a trolley system that is mounted on the cable, using the force of gravity to traverse the line from one end to the other. Some zip lines go over canyons, some through tree canopies, while others start on man-made towers that participants climb to initially gain height. All this sounds technical and, of course, does not describe the fun part — the absolute thrill of flying through the air and screaming with delight! And don’t worry, we do teach you how to stop.
