I've previously posted an incredible video about slacklining across the 3 Salazes, here are more videos of slacklining in Reunion, including a world record!
The first shows Swiss Raphael Bacot and his Reunionnese counterpart Kevin Borg of Slackline 974 crossing a suspended midline against a background of exploding waves on the south coast, at Cap Mechant.
The second takes place in the isolated mountain cirque of Mafate and shows Kevin crossing a 40-metre high gorge at Trois Roches. Both these exploits were filmed using a mixture of images from a Gopro (from the slack liners' point of view) and aerial shots by drones.
The third video shows Nathan Paulin setting a world record on 9th June 2015 by crossing the longest slackline in the world, 403m long and 250 metres above ground at the Cassé de la Rivière de l'Est. It took him 23 minutes to walk the 403m and he was filmed by Les six patates. (A few weeks later he set a new world record highline at the Natural Games in Millau, France – 469m).
