The stuntman has previously traversed Times Square, the Grand Canyon gorge and Niagara Falls on tightrope. But tonight he attempted his biggest ever challenge – an 1800-foot walk over the Masaya Volcano in Nicaragua.
The stunt marked Mr Wallenda’s “longest and highest highwire walk ever attempted,” according to ABC.
He told Good Morning America hours before the stunt: “The reality of it is I’m risking my life, and we’re dealing with mother nature.”
The dare devil wore a gas mask and oxygen tank during the walk, working against toxic gas and wind which impacts on aerodynamics and visibility.
His wife aerialist Erendira also did her own stunt above the active volcano.
She hung above the molten lava wearing a gas mask while managing to move her body into impressive contortions.
Commenting after her stunt on ABC Erendira said: “At first I was nervous but then I remembered ‘no, this is what you do’, I could hear my music and then I just calmed down.”
She also described the stunt as a “once-in-a-lifetime experience.”
ABC also spoke to famed Geologist and Volcanologist Jess Phoenix about Mr Wallenda’s stunt.
She said: “This volcano is one of the most active on the planet. It’s currently erupting right now.”
Ms Phoenix added that her biggest concern was the “plume of volcanic gas” known as “volcanic smog” which is made up of acidic gases making it hard to see and breathe.
She added: “This is one of the harshest environments on the planet.”
Mr Wallenda appeared to be wearing a zip wire for safety.
Mr Wallenda moved slowly but precisely across the rope.
During the walk, the stuntman could be heard describing the experience as “amazing”.
The fog from the fumes appeared to be thick above the crater, making visibility difficult.
The stuntman could also be heard joking with his crew as he spoke to them into the microphone attached to him.
He joked: “Kinda ridiculous what you have to do to get a good view of a volcano these days.”
