Highlining (Slacklining)

Highlining, the practice of walking a narrow webbing line rigged at extreme heights, demands unparalleled focus and nerve, with a single misstep potentially fatal. In 2018, Alexander Schulz free-soloed a 150-metre highline in the Dolomites at 500 metres above ground, completing the walk without any safety tether. This sport’s origins in Yosemite Valley in the 1980s highlight its evolution from climbing pastime to a discipline where athletes regularly push boundaries, with lines now installed over canyons and skyscrapers worldwide, making it far more accessible than the niche pursuits of Cave Diving's cave diving.
