Nik Wallenda becomes the first man to successfully walk across the Grand Canyon on a tight rope.

Nikolas Wallenda is an American acrobat, aerialist, daredevil, high wire artist, and author. He is known for his high-wire performances without a safety net. He holds 11 Guinness World Records for various acrobatic feats, and is best known as the first person to walk a tightrope stretched directly over Niagara Falls. Wallenda walked 1,800 feet (550 m) on a steel cable over Masaya Volcano in Nicaragua, his longest walk, on March 4, 2020.

Skywire Live with Nik Wallenda is a Discovery Channel special that aired on June 23, 2013. The special was billed as a highwire walk across "the majestic Grand Canyon". Interpretations varied as to whether the actual location – the Little Colorado River Gorge in Navajo territory outside Grand Canyon National Park's borders – was truly part of the Grand Canyon.

The Grand Canyon is a steep-sided canyon carved by the Colorado River in Arizona, United States. The Grand Canyon is 277 miles (446 km) long, up to 18 miles (29 km) wide and attains a depth of over a mile.

Tightrope walking, also called funambulism, is the skill of walking along a thin wire or rope. It has a long tradition in various countries and is commonly associated with the circus. Other skills similar to tightrope walking include slack rope walking and slacklining.
