Argentière’s ski season is one of the longest thanks to its altitude and north-facing aspect, lasting from early December through to the beginning of May. December and January are the most reliable months for snowfall, coinciding with the holiday season. This is also the coldest time, so wrapping up warm is a must up-high. This is also the busiest period, along with February. March and April bring longer and warmer days, along with less crowded slopes and also the chance to pick up a late season bargain.
