The Stillup Basin is an artificial lake in the Zillertal valley, located in the idyllic Zillertal Alps Nature Park.
From 1965 to 1977, with a beak, the Stillup Basin, belonging to the power plant of Mayrhofen, was established. The artificial lake is fed by the homonymous river, originating in the Zillertal Alps, and by the melt-water of four mighty glaciers in the surroundings. Moreover water is passed on to the power plants of Häusling and Rosshag, which finally reaches the power plant of Mayrhofen, where it is used for the production of electricity. The 28 m high Stillup dam dams up the waters.
The Stillup Basin is accessible via the Stilluptal valley, the shortest of the four side valleys, stretching fan-shaped in the surroundings of Mayrhofen. An 8 km long toll road starts behind the Ahornbahn funicular in Mayrhofen and takes to the Wasserfall tavern along several hairpin bends. Also the public bus runs between Mayrhofen and the lake, a private shuttle service takes you even to the Grüne Wand refuge. The wild romantic Stilluptal valley in the Zillertal Alps Nature Park is, however, not only known for its lake, but is also a well-frequented and idyllic excursion destination, above all in summertime. The genuine valley is also very popular with cyclists and hikers.
The tours take you for example to the Grüne Wand (1,438 m asl) and the Kasseler (2,178 m asl) refuges. The latter makes you enjoy a fabulous view on the Monte Lovello. Further destinations are the Stilluphaus refuge (1,194 m asl) or the waterfall at 1,130 m asl, the largest waterfall of the Stilluptal valley, also known as the "Coronation". And maybe you can observe chamois, deer or marmots! A further example for the biodiversity are the 500 butterfly species in the valley...
