Watch: Slacklining 2,500 Feet Above Yosemite Falls

Yosemite National Park is known to be a place that attracts outdoor thrill seekers. In fact, renown rock-climber Alex Honnold completed the first ever rope-free ascent of Yosemite’s El Capitan earlier this year. But now a slackliner is making waves with a viral video.

A mysterious adventurer posted the below video of someone slacklining across Upper Yosemite Falls, about 2,500 feet high. The footage is terrifying, but even more scary is the fact that the person falls at about the 1:54 mark of the video.

Warning: if you’re scared of heights, this video may not be for you. Check it out:

The daredevil was attached to the slackline, making the danger factor much less severe. But dang, that still takes a lot of guts.
