Walking above the ground or mid-air on a rope or wire is not so uncommon a sight. But slacklining is an exclusive mid-air adventure that involves a practice of walking on stretchable nylon rope.

Slackliners often indulge in the mid-air adventure at a great height over ground (highlining) and water (waterlining).

An Austrian slacklining enthusiast Michael Kemeter, who has set many records in highlining and waterlining, did a wire-walk, mid-air between two ledges of Austria’s highest peak recently.

In 2010, Kemeter, along with some of the best slackliners of the world, did the first ever longest highline above Cascade Falls at Yosemite National Park in California.
