Participants in a zip wire, also known as a zip line, slide down a hanging rope while attached to a pulley system. It is a popular adventure activity that is frequently seen at outdoor recreation areas, adventure camps, and other locations.

A zip wire is a long cable that connects two points, usually on a hill or across a canyon. Riders typically begin at a higher height, and a harness and pulley system secures them to the rope. Gravity and the momentum generated by the first shove propel them as they slide down the cable to the other end.
