Chacaltaya typically opens around June 1 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 Chacaltaya usually runs until September 30. 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.
