Cima di Castello, Summit in Grisons, Switzerland and Italy

Cima di Castello is a 3,379-metre summit in the Bregaglia Range, on the border between Italy and Switzerland. Its peak rises between the Albigna valley and Forno Glacier in Graubünden and Val Mello in Lombardy. It is the second-highest mountain of the Bregaglia Range, after Monte Disgrazia.

Cima di Castello is the second-highest summit of the Bregaglia Range, after Monte Disgrazia, and lies on the Italy–Switzerland border between Lombardy and Graubünden. The Italian Wikipedia places it at 3,388 m in the Bernina Alps of the Western Rhaetian Alps, while the English article gives 3,379 m. Its two standard routes were established from Vicosoprano via the Albigna hut and from Val di Mello via the Allievi-Bonacossa hut.

The name Castello, "castle", refers to the mountain's castle-like snowy dome, not to any building. The peak is less known than lower neighbours such as Pizzo Badile and Pizzo Cengalo, so its normal routes see fewer parties. It lies on the watershed between the Albigna and Forno Glacier valleys in Graubünden and Val Mello in Lombardy.

Two approach routes exist: from Vicosoprano in Switzerland via the Albigna Hut (2,340 m), or from Val di Mello in Italy via the Allievi-Bonacossa Hut (2,385 m) in Val di Zocca. From the Italian hut, climb north, then cross the glacier northeast parallel to the ridge; the final snow slope reaches the summit at F+ grade. An ice axe and crampons are needed even in summer, along with good fitness and alpine experience.

Despite being the second-highest mountain in the Bregaglia Range, Cima di Castello is less well known than lower neighbours such as Pizzo Badile and Pizzo Cengalo. Its snowy summit dome is reached by a final slope graded F+, and an ice axe and crampons are needed even in summer.
