Caumasee, Switzerland

Fed by underwater aquifers the lake varies in depth of 4-5 metres throughout the year. The lake is located in a huge Forest that was allowed to remain on the agriculturally useless debris area of the fascinating prehistoric rockslide in the alps region.

Because of it’s shallowness water temperature in summer is at an average 21 Celsius, with a maximum around 24 Celsius. I got in but Rudy gave it a miss. He’s not much of a swimmer, more of a dipper.

Man, he doesn’t like those sharp little pebbles! He didn’t appreciate walking to the lake. “Why can’t we use the funicular? It was refurbished in 1988”
