The standard equipment on Via Capricorn includes good footwear, a water bottle and a warm jacket for higher climes, but above all: a binoculars. At the latest after the steep ascent from Alp Biggenmad up to Alperschälli, the binoculars are at hand. Because here the ibexes can be observed particularly often.
Lake Urdensee is situated on 2'249 m asl in a side valley of the middle Schanfigg between the municipalities of Arosa and Vaz/Obervaz, as well as the alp region Urder Augstberg. It is surrounded by the mountains Plattenhorn, Hörnli, Hörnligrat, Tschirpen, Parpaner Weisshorn and Parpaner Schwarzhorn.
The lake is located two kilometers from the village of Pigniu. It is about 1.5 kilometers long and about 250 meters wide. It is fed by some nameless mountain streams. Around the lake leads an easy-to-walk walking or walking path. For the circumnavigation you need about an hour. On the west side, several large waterfalls plunge into the valley in the rear part.
