Daredevil To Walk Tightrope Across Grand Canyon Live On TV

Daredevil Nik Wallenda, descendent of the famed Flying Wallendas circus family, is planning to walk a tightrope strung across the Colorado River Gorge just outside the boundaries of Grand Canyon National Park this Sunday, Associated Press reports.

Wallenda, who successfully walked across Niagara Falls on a tightrope last year, will attempt to walk a third of a mile across a wire suspended 1,500 feet above the chasm. But unlike his Niagara Falls stunt, Wallenda will not be wearing a safety tether – and there won’t be a safety net, either.

The seventh-generation performer’s family has had its fair share of tragedy. Several of his family members have perished while performing, including his great-grandfather, Karl Wallenda, who fell to his death while walking a tightrope between two towers of a hotel in Puerto Rico at the age of 73.

Wallenda estimates it will take him about 30 minutes to cross the gorge. Tune in on Sunday at 8 p.m ET to the Discovery Channel to watch the live stunt, or watch it online.
