Munt Pers, Alpine summit in Graubünden, Switzerland.

Munt Pers is an Alpine summit in the Bernina Range at an elevation of 3,207 meters. The peak stands within the Upper Engadine valley system of eastern Graubünden.

The name Munt Pers comes from a Romansh legend: a herdsman named Aratsch, grieving for Annetta of Pontresina, rode into the glacier, and the alp was later cursed and covered by ice, leaving the "lost mountain". The peak's recorded routes run from Diavolezza (2973 m) and from Morteratsch station (1896 m).

The name Munt Pers means "lost mountain" in Romansh, from munt (mountain, alpine pasture) and pers (lost). A local legend, Die Jungfrau vom Morteratsch, explains it: the maid Annetta died of grief, her returning lover Aratsch rode into the glacier, and her curse left the alp barren until the advancing glacier buried it.

The shortest route starts at the Diavolezza cable car top station (2,973 m), not the valley station, and reaches the summit in about one hour on a white-red-white marked trail (T3). Longer ascents run from Morteratsch station (1,896 m, 4 hours, T5) or from Bernina Diavolezza station (2,093 m) via Lej da las Collinas. In winter the Diavolezza route is rated WS− and takes about 1½ hours.

The farthest point visible from the summit is the Wetterhorn (3,692 m) in the Bernese Alps, 143 km to the west. The peak lies entirely within Pontresina's municipal area, ringed by the Val Bernina, Val Morteratsch and the Pers and Morteratsch glaciers.
