Col des Montets (elevation 1,461 m or 4,793 ft) is a mountain pass in the French Alps in the Haute-Savoie department of France. It is on the road between Chamonix, the Swiss Col de la Forclaz and Martigny in the canton of Valais, Switzerland. The pass is generally open in winter, but it can be closed in extreme weather and frequently requires snow chains and/or winter tires. Conditions can be checked with Chamonix tourist office. The railway tunnel of the Saint-Gervais–Vallorcine railwayhas been modified to also carry road traffic on a convoy basis between trains when the pass is closed.
