Main image

Monte Leone is a high Alpine peak in the Lepontine Alps, located in the Valais region of Switzerland near the Swiss-Italian border, with an elevation of about 3,553 metres. It is the highest point of the Monte Leone massif and a prominent summit above the Simplon area.

The mountain is known for steep faces and glaciated approaches in its higher sections and is a target for mountaineers operating from the Simplon Pass and surrounding valleys. Ascents require alpine experience and appropriate equipment.

The massif forms part of the high alpine landscape between the canton of Valais and Piedmont in Italy, giving it prominent local relief and visibility from valley approaches.

Monte Leone sits above the Simplon region in southern Valais, close to the Simplon Pass road and rail links that cross between Switzerland and Italy.

  • Elevation: Summit elevation is 3,553 metres, making it one of the highest peaks in the Lepontine Alps and dominant above the Simplon region.

How to Get to Monte Leone #

Monte Leone sits on the Swiss-Italian border in the Simplon region. The usual approach is via the Simplon Pass area: drive from Brig (Valais) or from Domodossola (Italy) onto the Simplon road and use the local trailheads in the pass or adjacent valleys to begin mountain routes. Brig is the nearest major rail hub; from there local roads lead to the Simplon Pass where hiking routes up Monte Leone start (alpine equipment and route planning are required).

Tips for Visiting Monte Leone #

  • Attempt Monte Leone in the stable summer months (July-September) when snow and glacier hazards are reduced and high-alpine huts are operating.
  • Access is commonly made from the Simplon Pass area; if you plan to use a mountain hut or bivouac book it ahead of the main season and confirm approach routes from the Swiss or Italian side.
  • The upper slopes can include glacier or snow sections depending on the year-only attempt the summit with proper alpine equipment or with a certified guide.
