Dammastock

Dammastock is the highest peak of the Urner Alps in Switzerland, rising above the Göschenen valley in the canton of Uri. At 3,630 m it is also the top point of the whole canton. Its summit ridge marks the line between Uri and the canton of Valais.

Where is Dammastock?

The mountain belongs to the Winterberg massif in central Switzerland. The cantonal border follows its crest, and the massif is shared between the municipalities of Göschenen (Uri) and Obergoms (Valais). A few kilometres to the north, near the Eggstock, the borders of Bern, Valais and Uri meet. Some sources place the peak in the Bernese Alps, but it is usually described as part of the Urner Alps, where it is the tallest summit.

What is there to see?

Dammastock overlooks several large glaciers: the Damma Glacier, the Trift Glacier and the Rhône Glacier, source of the river Rhône. The scenery is pure high mountain: ice, rock ridges and high passes, with no casual footpaths to the top. For most visitors the summit is a climber's objective, while the massif and its ice can be admired from lower in the valley.

How do you climb it?

This is an alpine expedition rather than a hike. The route crosses glaciers, so you need a rope, crampons, an ice axe, experience in roped travel and a good read on conditions. Most parties start from the Dammastock hut (Dammahütte); another approach comes from the Valais side near Hotel Tiefenbach by the Furka Pass. Beginners should hire a mountain guide.

When should you go?

Climbing season runs from summer into early autumn, when huts are open and glaciers are workable. Outside that window conditions are wintry and call for full ski-touring or mountaineering experience. Check the forecast and the current glacier state before setting out.

How do you reach Göschenen?

Göschenen sits at the northern portal of the Gotthard road tunnel, on the Gotthard railway and the A2 motorway. From there the road climbs up the Göschenertal, making the village a practical base for trips into the massif.
