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.

one of the most beautiful mountain lakes I know. Picturesque location with the ski flying hill in the background. I could stay here all day. Due to the existing seaside resort including gastronomy, the lake is also an ideal destination for families on warm summer days. It is also the ideal starting point for great hikes to the Söllereck
