The smallest of the six bathing lakes in the west of Kufstein, a popular hiking destination, is called Pfrillsee.
The Pfrillsee, with its 1,8 hectares the smallest of the six lakes in the west of Kufstein, does not have an overground inlet - it is fed by subterraneous springs. However, this lake is a popular destination for hikers, not least because from the southern lakeside you can enjoy a beautiful view on Kufstein, located 100 m lower than the Pfrillsee, and its tributary valleys.
Beside the Hechtsee, Längsee and Egelsee, also Lake Pfrillsee belongs to the "Thierberg Lakes", tectonic phenomenons and basins that the Inntal Glacier has cleared out in the last Ice Age. Today, the Pfrillsee is in private hands, but it is freely accessible for bathing and hiking.
About 100 m from the small lake, there is a reeds pond, the Haarsee. This little pond was separated from Lake Pfrillsee by a rockfall long time ago. Take care: In the surroundings of these lakes, crossed vipers turn up from time to time, as it is a poisonous serpent native of Austria.
