Piz Bernina is the highest mountain of the Eastern Alps and the highest point of the Bernina Range. It is also the farthest easterly mountain higher than 4,000 m in the Alps and the fifth-most prominent peak in the Alps. Piz Bernina is located near St. Moritz, one of the most well-known resorts in the Swiss Alps. The normal route starts from the Rifugio Marco e Rosa, located at 3,600 m above the Fuorcla Crast'Agüzza. The north ridge, called the Biancograt or Crast Alva (both meaning White Ridge), is the most well-known and attractive route to the summit, and is much more difficult than the normal route. The route starts from the Tschierva Hut (2,584 m) in Val Roseg, accessible from Pontresina. The Biancograt itself starts at the Fuorcla Prievlusa (3,430 m) and leads to Piz Alv (3,995 m). To reach the summit, the Bernina gap must to be traversed.
