TELEVISION Watch Nik Wallenda as he attempts to tightrope walk across the Grand Canyon

Nik Wallenda, King of the High Wire and seventh generation descendent of the legendary Wallenda Family acrobatic troupe, is on a mission — that of traversing the majestic Grand Canyon without a harness.

Discovery Channel will air the nail-biting event live on Monday, June 24, at 5.30 a.m. with a repeat at 8 p.m.

Wallenda will tightrope walk the distance. At 1,500 feet above the Little Colorado River, this height is the highest that he’s ever attempted before. In 2012, Wallenda became the first person to tightrope walk directly over Niagara Falls from the U.S. to Canada at a height of 200 feet.

“The stakes don’t get much higher than this. The only thing that stands between me and the bottom of the canyon is a two-inch thick wire. I’m looking forward to showing the audience a view of the canyon they've never seen before,’ says Wallenda. Thirty four-year-old Wallenda, says that this latest event will be the fulfilment of a lifelong dream to walk at such a great height as well as a chance to honour his great-grandfather, Karl Wallenda, who died after falling from a tightrope in Puerto Rico in 1978.
