Glacier skiing explained

Glacier skiing means skiing on a permanent body of high mountain ice, which is the most snow sure terrain you can ski and the only way to ski reliably in summer. In Europe a handful of glaciers, led by Zermatt, stay open through the summer, while many top resorts use their glaciers to guarantee snow from October to May. The tradeoffs are real: terrain is limited, mornings are best because the surface softens to slush by midday, and you must respect the mountain and the altitude.

The short answer: ski a glacier when you want guaranteed snow, whether that is summer turns in July or a snow sure week in a thin early season. A glacier is permanent ice high enough to hold snow when lower slopes are bare, so resorts build lifts onto them to extend the season at both ends and, in a few cases, run them year round. The catch is that glacier terrain is usually small, the best snow is early in the day, and crevasses make staying on the marked piste essential.

What a glacier actually is, and why it skis well

A glacier is a slow moving mass of ice formed where more snow falls each year than melts, often sitting above roughly 2,800 to 3,000 m in the Alps. Because that altitude stays cold, the glacier keeps a skiable snow cover long after lower pistes have melted out, which is why glacier resorts can open in October and, at the highest, ski right through summer.

The skiing on a groomed glacier piste feels much like any high mountain run, wide and usually gentle to moderate in pitch. What is different is underneath you: the ice is riven with hidden crevasses, so the pisted, marked area is fenced and patrolled and you must not stray off it without a qualified guide and proper equipment.

Where to ski a glacier, and when

For summer skiing, Zermatt is the surest in Europe, with snow held high enough to ski into August in a normal year, while Les Deux Alpes has one of the largest summer glacier areas in France. For snow sure winter and shoulder season skiing, Tignes and Val d'Isere share the Grande Motte glacier, Solden in Austria opens two glaciers from autumn, Saas Fee skis high and long, and Cervinia links to the Zermatt glaciers from the Italian side.

Use a glacier for guaranteed snow at the edges of the season or in summer. In the depth of winter, January and February, you do not need a glacier for cover, but the high glacier pistes still ski well and stay reliable in a poor snow year.

What glacier skiing costs

In summer, a glacier day pass is usually cheaper than a full winter pass, often in the range of around $50 to $70, because only the glacier sector is open and lifts run mainly in the morning. A summer ski trip is therefore inexpensive on snow but is best treated as a few hours of skiing followed by other mountain activities, not a full day on the pistes.

In winter the glacier is simply part of the normal resort and covered by the standard pass, which runs from around $60 at value resorts to $90 plus at the big names. The real budgeting point is time, not money: plan to be on the glacier at opening and off it by early afternoon, when the surface turns to heavy slush.

How to ski a glacier well and safely

Three rules cover most of it. Go early, because overnight cold firms the surface and it skis beautifully at opening, then softens to tiring slush by late morning, especially in summer and spring. Stay on the marked, patrolled piste, because the ice around it hides crevasses, and only venture off with a qualified mountain guide and crevasse rescue equipment. Protect yourself from the sun and altitude, since glaciers are high and the reflected glare is fierce, so high factor sun cream, good goggles and water are not optional.

Altitude is the quiet factor people underestimate. Glacier pistes often top out above 3,000 m and some reach close to 3,900 m, so give yourself a day to acclimatize, take it easy on the first morning, and read our guide on how altitude affects your ski holiday.

Questions worth asking

Glacier skiing FAQs

Where can you ski on a glacier in summer in Europe?

Zermatt in Switzerland is the surest, with snow held high enough to ski into August in a normal year, and Les Deux Alpes in France has one of the largest summer glacier areas. Saas Fee also skis through much of the year. Summer skiing is morning only and the terrain is limited.

Is glacier skiing safe?

The marked, patrolled glacier piste is as safe as any high mountain run, and you should stay on it. The danger is off piste, where hidden crevasses make a fall potentially serious, so only leave the markers with a qualified mountain guide and crevasse rescue equipment. Sun and altitude are the other real risks to manage.

Why is glacier snow better early in the day?

Overnight cold refreezes and firms the surface, so the piste skis fast and smooth at opening. As the sun climbs, the snow softens to heavy, tiring slush, especially in summer and spring. The practical rule is to be on the glacier when the lifts open and off it by early afternoon.

Do you need special equipment for glacier skiing?

Not for the groomed piste, where normal ski gear is fine. You do need strong sun protection and good goggles because the high altitude glare is fierce. For any off piste glacier travel you need a guide, a harness, rope and crevasse rescue training, which is mountaineering rather than resort skiing.

Is glacier skiing good for beginners?

Many glacier pistes are gentle and well groomed, so they can suit beginners, but the altitude can tire newcomers quickly and summer slush is hard work. A beginner is usually better off on a high, snow sure resort piste in winter than chasing a summer glacier session.

Are Alpine glaciers shrinking?

Yes. Alpine glaciers have retreated significantly in recent decades, which has shortened or ended some summer skiing operations and reshaped a few pistes. The highest glaciers like Zermatt remain the most resilient, but glacier skiing is more weather and year dependent than it once was, so check current opening before booking.
