Nestled between massive rock faces, the most well-known valley is filled by the emerald green Königssee. It is only accessible with the electric boats of the Königsseeschifffahrt or by foot over the summit regions of the surrounding mountains. Seafaring, fishing and servicing the alpine pastures are some of the traditional uses of the lake. Behind it is the core zone of the national park with its unique flora and fauna, which has been subject to very strict nature conservation requirements since the reserve preceding today’s natural park was founded in 1928. Catch a boat to explore the peninsula St. Bartholomä with its historical buildings of the pilgrimage church and restaurant, the Eiskapelle (“Ice Chapel”) at the foot of the Watzmann east face, lake Obersee with alpine pasture Fischunkealm as well as Germany’s tallest waterfall, the Röthbachwasserfall (400m).
