Blausee as the name suggests - is a blue lake nestled in the Bernese Alps that holds a unique story. Legend has it that these warm, deep-blue waters were named for a beautiful maiden who drowned in the lake after her heart was broken. The crystal clear waters are fed from subterranean springs making Blausee one of the most picturesque lakes in Switzerland. Lake Blausee's mountain spring water is ideally suited for the farming of rainbow and salmon trout. Swimming is therefore strictly forbidden but you can savour these delicacies at the lake's shore. Those who want to explore the water can do so by glass-bottom boat.
