Piburger See lake is the result of a natural catastrophe; today it is the landmark and gem of Oetz. Originally the lake's hollow was an old valley parallel to the Ötztal valley. After the last ice age a massive rock slide blocked the valley at its south-eastern end and covered its entire bottom. That's why water impounded and formed a lake. Because of its location amidst crystal rock Piburger See lake holds very soft water. In mid-summer surface temperature reaches up to 24°C. Because of its scenic location the lake is a popular destination for hikers and swimmers.

The shores of Piburger See lake are steep and partly rocky. At the southern end of Piburgersee lake is a swimming bath with large sunbathing areas. Swimming in the lake is only recommended in this area. The swimming bath features a rowing boat rental; watch the mountains' reflection in the lake from a wooden boat.

The road to the lake leads to a car park in Piburg which is subject to charges. From there you have to walk along a lovely valley along the Piburg brook. A circuit trail leads around the lake through the forest. Enjoy a break directly at the lake or in the hamlet of Piburg. Several hiking trails make the area of Oetz and Habichen accessible.
