The Freibergsee is located at an altitude of 930 meters. With a water surface of around 16 hectares, it is the largest high mountain lake in the Allgäu. The Freibergsee has no visible inflows or outflows. Its periodically fluctuating water level is regulated by underground inflows and outflows. The lake was formed during the ice ages when the ice masses of the Stillach glacier towered 700 to 800 meters high above the current location.

This unique natural monument is located in Oberstdorf and is the deepest rock gorge in Central Europe. It is one of the most impressive geotopes in Bavaria! It is also one of the most popular attractions in the Allgäu and stretches from Oberstdorf Tiefenbach to the neighboring Kleinwalsertal. Access is possible from both sides. A trip is worthwhile at any time of the year - even in rainy weather, because the more water flows, the more impressive the Breitachklamm appears. See: https://www.breitachklamm.com/
