Highlining is an extreme sport that involves walking on a tensioned rope or webbing, typically set high above the ground. This activity is a variation of slacklining, where the line is anchored between two points, often across canyons, cliffs, or other elevated locations. Participants use a harness and safety gear to minimize risks while balancing on the line. The sport requires a combination of physical skill, mental focus, and a strong understanding of safety practices. Highliners often practice in various environments, from urban settings to remote natural landscapes, and the activity has gained popularity among adventure enthusiasts and thrill-seekers worldwide.
