Lake 16 is Croatia's largest national park. It was listed as a World Heritage Site in 1979. The team leader said it was Jiuzhaigou in Europe. The park consists of 16 lakes large and small, so it is called the Sixteen Lakes National Park. It is divided into two lake areas, the upper lake area has twelve lakes, the lower lake area has four lakes. Sixteen lakes are banded in the valley, the two sides of the peaks are continuous, and there are wooden bridges between the lake and the lake. The crystal crystal of the lake is bright, reflecting the lush green, into sixteen emerald-like gems, beautiful.
