The Böchtesgaden National Park where the upper lake of King Lake is located is a famous tourist attraction in Germany. The King Lake is famous for its clear lake water. It is considered the cleanest and most beautiful lake in Germany. It is known as Jiuzhaigou, Germany. It is not as big as Jiuzhaigou. Can't row by yourself, so taking a boat trip is the choice for most people. King Lake is sandwiched between steep peaks and cruise ships that pass through it, with the feel of a Nordic fjord. When the cruise ship comes near the rock wall, the captain will blow up the trumpet. For foreign tourists who do not drive, traffic here is not very convenient.
