A valley with character - the original Durnholz
Durnholz is a small hamlet with traditional farmhouses, a pretty church with frescoes and plenty of authentic charm. The village conveys an impression of how life in the South Tyrolean mountains used to be – original, simple, slowed down. The combination of nature and living tradition gives the valley a very special atmosphere
Interesting to know: According to a South Tyrolean legend, a farmer from Durnholz disregarded the end-of-work bell and spoke mockingly, even if the lake should swallow up his property. The next morning, his house and farm were indeed submerged in the lake.
Activities around the lake

In the winter months, the Sarntal Valley is a popular holiday destination for active travellers, with dreamlike ski tours, snowshoe hikes and much more.

Fishing fun
Lake Durnholz is almost triangular in shape. Its two main tributaries are the Großalmbach and the Seebach. The outflow is via the Durnholzer Bach. If you have a fishing licence and buy a day ticket from the Hotel Fischerwirt, you may be lucky enough to catch a magnificent trout while fishing in summer.
Hiking with a view
From an easy walk around the lake to a family-friendly hike to the Seeb Alm and a challenging mountain tour to the 2,741 m Jakobsspitze, hiking trails for every taste start from Lake Durnholz. Mountain bikers can also choose from a variety of routes: for example, a circular tour from Sarnthein to the lake and back or a challenging day tour starting and finishing in Feldthurns in the Eisacktal Valley.
Winter idyll & ice skating
In winter, ski tourers and snowshoe hikers can enjoy a variety of routes that lead to the panoramic peaks and ridges above the lake. As soon as the ice cover is thick enough in winter, Lake Durnholz is transformed into a beautiful ice skating rink.
