Mont Collon is a mountain in the Pennine Alps of Valais, Switzerland, reaching roughly 3,637 metres in elevation. It is noted for its prominent, steep faces and glaciated slopes.

The mountain offers technical alpine routes and glacier travel, with routes commonly approached from the Arolla valley. Its north face and the adjacent glacier fields are principal features for climbers and ski mountaineers.

Alpine exploration and mountaineering development in the 19th and 20th centuries established Mont Collon as a classic objective for experienced climbers; huts and routes in the Arolla area support ascents.

  • Height and climbing: Rises to approximately 3,637 metres and is notable for a steep, glaciated north face that is a target for experienced alpinists.
