Upper Yosemite Falls is among twenty highest falls in the world. The trail to the top of the fall is one of the best hikes. The view of Yosemite Valley from the top is breathtaking. And equally impressive was the performance by this skywalker! While it takes one very strong heart to even climb on that rope, with high wind, he was able to maintain his balance on the rope and walk across the fall's mouth at almost 2500 ft!
