Meet Nik Wallenda
Nik Wallenda is known as "The King of the High Wire." He is the seventh generation of the legendary Great Wallendas and began walking the wire at age 4. He and his family have performed some of the most famous stunts in the world, but no one else has ever dared to take on the Grand Canyon.
Wallenda, 34, said the Grand Canyon event is the fulfillment of a lifelong dream to walk at such a great height as well as a chance to honor his great-grandfather, the legendary Karl Wallenda, who died after falling from a tightrope in Puerto Rico in 1978.
