La Rosière typically opens around December 12 each year. The opening date can vary by a few weeks based on early-season snowfall — some high-altitude runs open earlier.
The season at La Rosière usually runs until April 17. Higher glacier areas (if available) may stay open through spring and early summer.
Peak season runs from Christmas through the February school holidays, when slopes are busiest and prices highest. January mid-week and late March are the best value windows — excellent snow with fewer crowds.
