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 () in Val Roseg, accessible from Pontresina. The Biancograt itself starts at the Fuorcla Prievlusa () and leads to Piz Bianco (). To reach the summit, the Bernina gap - which repulsed Cordier, Middlemore, Jaun and Maurer in 1876 - has to be traversed.
