Christlessee

Highlight • Lake

The Christlesee is crystal clear and beautiful. It is fed by neighboring springs and never freezes over at any time of the year. However, the small lake is too cold for swimming, even in summer. The land above the lake is a water protection area, which is why the lake provides the best drinking water.
