A zip line is a recreational activity that involves a cable stretched between two points at different heights. Participants wear a harness attached to a pulley that glides along the cable, allowing them to travel from one end to the other, often at high speeds. Zip lines are commonly found in adventure parks, forests, and mountainous areas, providing an exhilarating experience while enjoying scenic views. Safety is a crucial aspect of zip lining. Operators typically ensure that all equipment, including harnesses and cables, meets safety standards. Participants usually receive a briefing on how to use the equipment properly and follow safety guidelines to minimize risks during the activity.
