Daredevil Nik Wallenda has become the first person to cross a section of the Grand Canyon on a tightrope without a safety net.

The 34-year-old, who describes himself as the "King of the High Wire", walked on a steel cable 457 metres above the Little Colorado River in the United States.

It took him just over 22 minutes to complete the over 426 metre distance.

High winds made the terrifying feat even harder, Wallenda had to stop twice during the record attempt.

For his next stunt the daredevil said he dreams of walking between New York's Chrysler Building and Empire State Building.
