Mount Kelimutu is a volcano near the small town of Moni, which is about 30 miles east of Ende, Indonesia. Within these Flores Islands of Indonesia sits a Volcano with three separate summit crater lakes.
The first of the three is located on the most western side of the islands. Its name is Tiwu Ata Mbupu or also know as the, Lake of the old People. The colors vary from time to time, but this particular crater lake is usually blue. The other two summit crater lakes are separated by a shared crater wall. Tiwu Nuwa Muri Koo Fai, the lake of young men and maidens and Tiwu Ata Polo,the Bewitched or Enchanted lake are usually green or blue. These summits are located on the eastern side of the Flores Islands, but unlike the western crater lake, these crater lakes turn to a more dark shade of color and more frequently. The cycles of colors are periodic and change with season.
Over the years, the three crater lakes have often changed color. Presently one of the lakes is black-brown, one is green, and one is currently changing from green to a reddish color. A reason may be the varying mineral contents of the water. Another explanation suggested by the locals is that the changing colors are caused by the neglected ancestral souls.
Many who have traveled to see this magnificent natural phenomenon agree that in the cold winter mornings, the crater lakes glow at their brightest. It may have to deal with the heat from the volcano reacting with the winter cold of Indonesia but, one thing is certain; any experience witnessing this would be a beautiful one.
