Discovery en Español to air live tightrope legend Nik Wallenda crossing over Grand Canyon

Nik Wallenda, known as The King of the High Wire, will traverse the majestic Grand Canyon, without using a harness. The Discovery Channel and Discovery en Español will capture the nail-biting, play-by-play live event on Sunday, June 23 at 8pm. Wallenda, 34, said that this latest event will be 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.Wallenda will tightrope walk higher than he’s ever attempted before at 1,500 feet above the Little Colorado River, a height greater than the Empire State Building. 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.
