Glacier Skiing and Ski Mountaineering
Ski mountaineering on glaciers is a discipline that sits between ski touring and alpinism. The same skis carry you up — but the terrain has crevasses, the weather changes faster, and a fall is no longer just into snow. Every classic European ski-tour traverse crosses major glaciers; learning to operate safely on them opens up a new dimension of the mountain year.
Where it begins
Most skiers come to glacier skiing through ski touring. Skinning up a groomed piste leads to skinning up wider valleys, which leads to glacier basins. The transition is gradual — but the skills required to manage crevasse hazard are a step change.
What changes on a glacier
Crevasses, opening in summer and bridged by snow in winter. Their location is rarely visible. The whole glacier is a single piece of moving ice; even gentle slopes can hide deep slots. A solo ski-tour on a glacier is a serious commitment.
Essential kit
- Harness: lightweight, worn for the whole glacier portion.
- Rope: 30 m of 7-8 mm dry-treated dynamic rope per team.
- Crevasse rescue kit: prussiks, pulley, ice screws, two carabiners, slings.
- Ice axe and crampons: in pack, ready.
- Avalanche kit: transceiver, probe, shovel — always.
- Helmet: optional in pure snow but recommended once ice screws come out.
Rope team technique
Three skiers on a rope, with 10-15 m between each, knots in the rope between skiers (some teams; others prefer none). Rope visible, not in the snow. Movement steady, with adjustable spacing for direction changes. Specific training before first deployment is essential.
Classic tours
- Haute Route (Chamonix-Zermatt). The classic 5-6 day glacier traverse.
- Berner Oberland traverse. Concordia to Lauterbrunnen via Konkordia hut.
- Otztal Tour. Austrian classic across the Otztal Alps.
- Norwegian Jotunheimen crossings. Quieter, less crevassed.
- Off-piste at Zermatt or Saas Fee. Lift access to high glaciers with guided programs.
Season and timing
April and May for spring corn snow and stable conditions in the Alps. June-July for summer skiing on high glaciers, but watch surface collapse. Avoid the deep winter — bottomless powder, hidden crevasses, short days.
Training
Take a course before relying on yourself. SAC and CAS in Switzerland, DAV and OAV in Germany/Austria, ENSA programs in France, NOLS or AMGA programs in North America. A 5-day glacier travel and rescue course gives the foundation; rope-team management requires more.
Avalanche overlap
Glacier terrain often holds avalanche slopes. Combine glacier travel training with avalanche education — the two are inseparable in winter ski mountaineering.
Recreational vs serious
Resorts like Hintertux, Stelvio or Zermatt offer summer skiing on groomed glacier slopes — no crevasse hazard, no equipment required beyond normal ski gear. That is glacier skiing too, just at the easy end.
