The crystal-clear lakes look sapphire, and they form a beautiful picture with the mountains. The waters of Kayangan Lake are particularly clear, with visibility of more than 40 meters. When you come to visit, make sure to bring snorkeling equipment. When you go snorkeling in the translucent lake, you can see the rocks and caves underwater very clearly. In addition, when riding a crab boat between the uninhabited islands, the location in the movie "King Kong" suddenly reappears!
