Tightrope walking is in my blood: Nik Wallenda

Nik Wallenda's high wire thrills 'in his blood'

Fresh off his latest feat walking the 400-foot Orlando Eye while it was in motion, tightrope walker Nik Wallenda said Thursday there's a simple answer for why he does what he does.

"It's my passion. My family's done this for seven generations and over 200 years now. As my family says, it's in our blood," he told CNBC's "Squawk Box."

While he has been walking tightropes since he was a toddler, the daredevil said he can still experience fear.

The walk along the rotating 6-inch frame of the Orlando Eye went great, he said, but as he walked up a rescue ladder, it started to collapse because it was not pinned properly.

"Those are the sort of things that wake you up, where that fear will jump in you," he said.

Likewise, he said his blindfolded walk across a tightrope strung between two Chicago skyscrapers last year was "really rough."

"I've been taught to focus on the other end. With a blindfold, without vision, it changed everything," he said.
