Glacier Skiing
What Makes a Glacier Ski Area Different
Most ski resorts depend on natural and artificial snow accumulating on steep mountain slopes during winter. Glaciers are different: they are bodies of ice that have persisted for centuries by accumulating more snow each year than melts. Ski areas built on glaciers can operate outside the conventional November-to-April window because the ice and high-altitude snow underneath remain reliably present through summer.
This year-round potential is the primary reason glaciers have been developed for skiing. Summer training camps for ski racing teams, late-season skiing for enthusiasts who cannot face the end of the snow, and shoulder-season tourism all depend on glacier-based operations. But skiing on glaciers involves hazards that do not exist on ordinary alpine terrain, and the physical reality of glaciers is changing significantly under current climate conditions — both facts matter if you plan to ski on one.
The Major European Glacier Ski Areas
The Stubai Glacier above Neustift in Austria is the largest summer ski area in Austria, operating year-round from a top elevation of 3210 metres. Its main season peaks in July and August, when Austrian and German national teams conduct pre-season training here. The ski area has around 35 km of marked runs at altitude, with lifts including a gondola from the valley at 1000 metres up to the glacier. The descent back to the valley — the Wilde Grube — offers around 1700 metres of vertical and is one of the longest ski descents accessible by lift in Austria.
Saas-Fee in Switzerland has operated a glacier ski area since 1979 from a top elevation of 3500 metres. It holds the unusual distinction of being Europe's highest completely car-free resort village, with the glacier lifts accessible by the Metro Alpin underground funicular from the village at 1800 metres. The summer operations attract national teams from across Europe and beyond. Saas-Fee's reliance on a single glacier sector has made it vulnerable to the visible ice retreat of recent decades.
Zermatt's Klein Matterhorn glacier, accessed by the Matterhorn Glacier Paradise cable car to 3883 metres, is the highest cable car station in the Alps and provides summer skiing on the plateau below. The connection to Cervinia in Italy through the shared Plateau Rosa glacier creates a cross-border summer skiing circuit that remains among the highest-altitude ski experiences in the world.
Tignes in France operates its Grande Motte glacier from June into August. The Grande Motte cable car reaches 3456 metres and gives access to a genuine glacier surface maintained for training and recreational skiing. Les Deux Alpes and Alpe d'Huez also operate smaller glacier zones, though the Les Deux Alpes glacier has seen significant retreat in recent summers.
Outside Europe: Glaciers with Skiing
Hintertux in Austria's Zillertal is unique in being the only ski area in the Alps with genuine year-round operation. It owes this to the specific geometry and accumulation characteristics of the Hintertux glacier, which has historically received more snowfall and retained snow better than comparable areas. The ski area reaches 3250 metres at the summit, with around 60 km of prepared runs. It is not the largest glacier area, but it is the most seasonally reliable in Europe.
In North America, Timberline Lodge on Mount Hood in Oregon provides summer skiing into late July most years. The Palmer Snowfield rather than a true glacier, it is maintained by heavy Cascade Range snowfall and has hosted US ski team training operations for decades. Mount Hood Meadows and Timberline together constitute the closest thing North America has to a dedicated summer ski operation.
Whistler Blackcomb operated the Horstman and Spearhead Glacier ski areas until recently, though the Horstman Glacier operations have reduced significantly as ice thinning has continued. The resort's summer skiing operations are now limited.
In the Southern Hemisphere, New Zealand's glaciers near Wanaka and on the South Island are primarily tourist attractions rather than ski destinations. The dedicated summer ski areas — notably the Remarkables and Mount Hutt — rely on high-altitude snow retention rather than glacier ice. Portillo in Chile and the Andes resorts offer July and August skiing, but on seasonal snowfields rather than permanent ice.
Crevasse Hazards and Glacier Skiing Safety
Glaciers move. Ice flows slowly downhill under its own weight, and this movement creates fractures — crevasses — where the ice stretches or bends around terrain features. On well-managed glacier ski areas, crevasses in the ski terrain are probed, flagged, and bridged at the start of each season, and the marked pistes are considered safe from this hazard as long as the markings are followed.
The hazard arises when skiers venture off the marked glacier terrain. Below the piste markers, probe coverage ends. Crevasses can be hidden under thin snow bridges that look exactly like solid glacier surface. A skier who breaks through a snow bridge can fall many metres into a crevasse — extraction from inside a crevasse is difficult even with companions present.
This is not theoretical. Accidents on glacier ski areas do occur, virtually always outside marked terrain. The rule on glacier pistes is simple and should be observed without exception: stay within the marked areas. The markers exist precisely because the terrain beyond them has not been checked.
Heavily crevassed glacier terrain — the kind encountered on the Vallée Blanche descent from the Aiguille du Midi above Chamonix — requires a guide. The Vallée Blanche covers roughly 20 km from the Aiguille du Midi to the Mer de Glace above Chamonix village, descends around 2800 metres of vertical, and crosses active glacier terrain with genuine crevasse hazard. Guides rope clients together for the most exposed sections and navigate around the crevasse field using routes that change year by year as the glacier shifts.
Climate Change and the Glacier Future
Alpine glaciers have lost roughly half their volume since the mid-twentieth century, and the rate of loss has accelerated. At current trajectories, projections suggest that the majority of Alpine glaciers at elevations below 3500 metres will be largely gone by the late twenty-first century. This is measurable in the operations of current glacier ski areas — surface retreat, thin snow years, and the seasonal windows available for skiing have all shifted.
Resorts have responded with snowmaking on glacier surfaces (an expensive and energy-intensive intervention), with geotextile coverings over the most vulnerable ice to slow summer melting, and in some cases with quiet reductions in advertised summer ski coverage. The question of glacier skiing's long-term viability at current scale is not resolved, and anyone planning a summer glacier ski visit should check current operational status directly with the resort.
