Pablo Signoret pulled off the feat over a canyon in Southwest China.
The Frenchman secured the Guinness World Record with a blindfolded walk of over 423 meters or about a quarter of a mile.
It took him about 25 minutes.
Other slackliners were also on hand to attempt the walk.
Slacklining is similar to tightrope walking, but the line is significantly less tensioned. This creates a bouncier sensation, similar to a trampoline.
