Guests walk along the 'Peak Walk' bridge during a media preview, at the Glacier 3000 in Les Diablerets, Switerland. Built between the Scex Rouge and View Point at an altitude of 3,000 metres (9,800 feet) the 107 m (351 feet) long and 80 cm (31 inches) wide hanging bridge is the first in the world to connect two peaks with one another.
