Casanna, Summit in Grisons, Switzerland.

Casanna is a 2,557-metre summit in the Plessur Alps of Graubünden, forming the natural boundary between the upper Prättigau and the Davos landscape. The municipal border of Klosters-Serneus and Davos runs over its top. It lies northeast of the Casanna Pass, west of the Gotschnagrat, and directly above the Casanna Alp.

The Casanna forms the natural boundary between the upper Prättigau and the Davos landscape; the municipal border of Klosters-Serneus and Davos runs across its summit. The summit lies northeast of the Casannapass and west of the Gotschnagrat, directly above the Casanna-Alp. The mountain rises to 2,557 metres in the Plessur Alps above Serneus and Klosters.

The summit marks the municipal boundary between Klosters-Serneus and Davos, so walkers cross from the Prättigau side into the Davos landscape. Directly below the top lies the Casanna-Alp, a summer pasture that gives the mountain its name. The ridge west of the Gotschnagrat is reached on foot from Serneus or Klosters.

The best hiking season is during warmer months when snow levels are lower and routes are clearer. Proper gear and mountain boots are important because conditions can change quickly in this terrain.

The summit marks the municipal boundary between Klosters-Serneus and Davos, and the border between the upper Prättigau and the Davos landscape. Directly below the peak lies the Casanna-Alp, while the Gotschnagrat with its cable car station rises to the east.
