Thanks to its very special color and the crystal-clear water, which has its source in subterranean springs, Blausee is one of the best-known mountain lakes in Switzerland. It is located in the midst of a 20 hectare large nature park with a landscape formed by a rock slide that led to the creation of the lake.
The lake and the special forest charmed local inhabitants and tourists early on. In 1885 Blausee was praised in a travel guide as a "jewel of a landscape immersed in magical forest solitude". Today the region is very accessible, thanks to walking paths, picnic spots and bonfire spots. There is a hotel with a spa directly on the shore of the lake, and next to it there is a successful organic trout farm.
