This mystical lake has become like a fairy tale, because not many tourists are ready to cross 500 kilometers of forest between the lake and the nearest town, Jambi.
The road trip takes at least 10 hours, followed by a four hour walk through the dense forest.
This luminescent lake has a width of about 30 meters and is surrounded by dense forest.
Although the blue water is dazzling, Kaco's lake is more mystical at night, when the water surface reflects the moonlight like a mirror.
Brave adventurers can swim in this mysterious lake, but do not expect to see the bottom.
Nobody ever dives down.
