Königssee

The Königssee is a natural lake in the extreme southeast Berchtesgadener Land district of the German state of Bavaria, near the Austrian border. Most of the lake is within the Berchtesgaden National Park. The lake is noted for its clear water and is advertised as the cleanest lake in Germany. For this reason, only electric-powered passenger ships, rowing, and pedal boats have been permitted on the lake since 1909. The surrounding sheer rock walls create an echo known for its clarity. On boat tours, it has become traditional to stop and play a flugelhorn or trumpet to demonstrate the echo.

St. Bartholomä, a famous pilgrimage church with an inn nearby, is located on a peninsula about halfway down the western lake shore.

Bad Reichenhall is a spa town, and administrative center of the Berchtesgadener Land district in Upper Bavaria. It is located in a basin encircled by the Chiemgau Alps. It is a traditional center of salt production, obtained by evaporating water saturated with salt from brine ponds.
