April 1st is April Fools' Day, we are a group of people fooled by the lake and mountains, this holiday is naturally happy. In the morning, we drive three hours to Königssee, a narrow and beautiful lake. It is located in the Bechtesgaden National Park, a famous tourist attraction in Germany. Known for its clear waters, King's Lake is considered the cleanest and most beautiful lake in Germany. There is also the former residence of Austrian actor Romeo Schneider, played by Sissi, the main character of the film Princess Sissi.
