Lake Antholz in the Antholz Valley is the third largest natural lake in South Tyrol and is located in the Rieserferner-Ahrn Nature Park. Surrounded by mountains, with turquoise-green water, it is one of the most popular destinations in the region. It is located at an altitude of 1642 m, its maximum depth is 38 m. It is over 900m long and 700 m wide, covering an area of 44 ha.

The lake can be circumnavigated in just 1.5-2 hours, thus inviting young and old to hike. Moreover, the path is prepared in such a way that it is also suitable for strollers. Around the lake, there is also a nature discovery trail, which provides information about the local flora and fauna in a vivid way. For example, you can learn about the different tree cones and rocks, what actually happens in an avalanche and what type of fish live in the lake. The lake is not suitable for swimming due to its coldness even in midsummer. Even in winter, a winter hike or cross-country skiing is possible on the 2.6 km long lake trail.

For a side trip at Obersee, you can continue from Lake Antholz directly across the state border to Staller Sattel in East Tyrol. However, it should be noted that this pass has the peculiarity of a one-way system. Traffic is alternately released in one direction because the road is very narrow and leads through a dense forest.
