He calls himself "King of the High Wire". Nik Wallenda announced plans to prove that title on Monday (March 18), with news of his next daring stunt; a tightrope walk over a section of the Grand Canyon, without a harness.

Wallenda, 34, will be higher than he's ever traversed before at 1,500 feet (457 meters) above the Little Colorado River

The daredevil said his latest attempt is a chance to honour his great-grandfather, Karl Wallenda, who died after falling from a tightrope in Puerto Rico in 1978.

The tightrope crossing will take place on June 23rd in a remote section of the Grand Canyon operated by the Navajo Nation Parks and Recreation and will air live on Discovery Channel.

In June 2012, Wallenda became the first person in 116 years to walk across the Niagara Falls on a high wire.
