-Depending on the temperature and weather conditions, bathing is possible from May / June.
-In winter, the lakes in the Three Lakes Area often freeze over. However, the thickness of the ice is not officially measured and stepping on the ice surface is at your own risk. Even if you watch others ice-skating or cross-country skiing on the ice - be careful!
