Glacier skiing has the advantage of being practiced all year round, even in summer. However, it requires great vigilance as the snow can hide crevasses and the snow bridges can prove to be particularly fragile. Falling into a crevasse is one of the major risks for skiers. It is, therefore, advisable to bring rescue equipment (carabiners, ice screws, straps, ascenders, etc.) and to master hoisting and hauling techniques.
