The trip begins with a leisurely cable-car ride; after just a few minutes you have reached the top of Switzerland’s longest glacier run. This glorious descent leads through a wilderness of snow and ice, and takes about 45 minutes. In contrast to many “smoothed out” glacier ski areas, this leads along the moraines of the Pers and Morteratsch Glaciers right to the foot of the glacier, and ends just in front of the sun terrace of the station of the Rhaetian Railway in Morteratsch. The piste is yellow marked on both sides, secured and not groomed. In terms of difficulty, most of it is equivalent to a red run; about 300 metres (330 yards) are equivalent to a black. The Diavolezza glacier run is open from ca. January until March (depending on snow conditions).
