One of the Skyliner risk-takers walking across a slackline between Paris' Two Towers

WATCH: Walk the line

Tightrope treading taken to dizzying heights

Hold your breath and whatever you do, don’t look down.

How else could you possibly approach treading a slackline 400 feet above the ground?

Adrenaline fiends the Skyliners love a risk or two and have made a name for themselves slacklining between two hot-air balloons and high above Mont Blanc in the Alps.

Watch them conquer the gut-wrenching stretch between the Levant (eastern) and Ponant (western) towers of Paris’ Les Mercuriales.
