Main image

Piz Bernina is a major peak in the Bernina Range of the Alps in the canton of Graubünden, Switzerland, and reaches an elevation of 4,049 metres making it the highest mountain of the Eastern Alps. It is a prominent objective for experienced alpinists in the region.

The mountain is known for its alpine routes, glacier scenery and ridgelines used by climbers and ski-mountaineers. Key local viewpoints and bases include the Morteratsch valley and the Diavolezza ridge, from which the south and east faces and surrounding glaciers are most visible. Glaciated approaches and high-alpine terrain mean climbs involve technical snow, ice and rock sections.

Piz Bernina is a natural feature formed by alpine uplift and glaciation; it has been part of the region’s mountaineering activity since the 19th century when systematic alpine exploration began. Over time routes, huts and cable-car access on nearby ridges have improved access for climbers and hikers while the peak itself remains a technical alpine summit.

The mountain sits in eastern Switzerland near the border with Italy, in the upper Engadin and near the Bernina Pass. The nearest well-known towns are Pontresina and St. Moritz, and the surrounding landscape is high-alpine with glaciers, cols and valleys.

  • Elevation: Rises to 4,049 metres and is the highest peak of the Eastern Alps.
  • Access: Common access points for climbers and sightseers include the Morteratsch valley and the Diavolezza area which offer glacier views and mountain transport links.
