Der Walchensee in Bayern (Bavaria), Southern Germany is one of the deepest and largest alpine lakes in Germany, 75 km south of Munich. The entire lake lies within the municipality of Kochel. The name Walchen comes from Middle High German and means “strangers”. All Roman and romanized peoples of the Alps south of Bavaria were known to locals as Welsche or Walche. On 16th-century maps, the lake is labelled Dicto Italico (“leading to Italy”), probably because the route through the Walchensee valley led through Mittenwald and Innsbruck (Austria) into Italy.
