Nik Wallenda walks the tightrope over Niagara Falls on June 15, 2012. The tense 1,800-foot journey took 25 minutes.
Nikolas “Nik” Wallenda described himself as The King of the Wire, and for good reason, too. He is American aerialist, acrobat, daredevil, and high wire artist. He is famous for his high wire performances without a safety net. Nik Wallenda has 6 Guinness World Records for several acrobatic feats, but he is best known as the first person to tightrope over Niagara Falls. This daring feat was years in the making as it took two years for him to get legal approval from Canada and United States. The stunt was broadcast internationally and it was the first time he had to wear a safety harness, which was required of him in order to get approved.
