At the Passo Stalle mountain pass, between South and East Tyrol, Lake Obersee is located at 2,016 m asl.
In the Valle di Anterselva in South Tyrol, the well-known Lake Anterselva is located, a popular excursion destination. Only few know, that this lake was also called Lake Untersee. Approx. 350 m higher, following the mountain pass road, Lake Obersee is located at the Passo Stalle on East Tyrolean terrain. This mountain pass separates South Tyrol from East Tyrol, thus Italy from Austria, and forms the border between the Vedrette di Ries and the Villgraten mountain groups.
The road to the Passo Stalle - a highlight for all motorcyclists - proceeds down into the East Tyrolean Defereggental valley. Lake Obersee is a nice destination to have a walk at a refreshing altitude or to start a mountain hike from there. The eponymous Oberseehütte mountain hut on its shore invites to stop in.
Lake Obersee is very rich in fish. Already 1,000 years ago fishing was done in the lake, as a diving expedition proved. Moreover, in 1999, the highest located ship find of Europe was made in 8 m depth. The about 1,000 year old dugout today can be admired in the Archaeological Museum Defereggen. And the lake is also well-known for the worldwide highest located dragon boat race, which takes place every year.
