People call him a daredevil, but Nik Wallenda says his tightrope walking adventures are an art form.

Wallenda performed his first practice walk this weekend on a tightrope he'll be using to cross Niagara Falls on June 15.

He slowly walked the two-inch steel cable strung between two cranes in front of the Seneca Niagara Casino, but stopped when he felt the cable moving beneath his feet.

The cable will require "some tweaking," but was otherwise fairly stable, Wallenda told CTV News Channel on Sunday.

"This was the first time I've done anything on a cable this size and it was a great experience," he said, expressing confidence about his much-hyped walk above the Falls.

While cable engineering and practice runs are essential for tightrope walkers, mental preparation is most crucial, Wallenda said.

Above all, "this is an art for me," he said.

Wallenda is a seventh-generation member of the famous daredevil family the Great Wallendas, also known as the Flying Wallendas. The family has performed all around the world.
