Tour de Don

Tour de Don is a mountain in the Chablais Alps that reaches approximately 2000 meters in elevation. The summit sits in a range that extends between the Swiss Valais region and the French Alps.

The mountain formed during the Alpine mountain-building period millions of years ago, when tectonic forces shaped the entire Swiss Alps region. These geological processes created the distinctive alpine landscape visible in the area today.

Local shepherds maintain traditional Alpine farming practices on the mountain slopes, continuing centuries-old methods of livestock management in the region.

The ascent is possible via marked trails from the village of Vionnaz and takes about four hours for experienced hikers. The best time to hike is during the warmer months when the paths are clear of snow and ice.

The summit sits just a few hundred meters east of the border between Switzerland and France. This proximity to the international boundary makes it an interesting point for those wanting to understand the Alpine border line.
