Kelimutu, Uniqueness Of The Lake In Three Colors


Kelimutu is a volcano, close to the town of Moni in central Flores Island of Indonesia containing three summit crater lakes of varying colors. Tiwu Ata Mbupu (Lake of Old People) is usually blue and is the westernmost of the three lakes. The other two lakes, Tiwu Nuwa Muri Koo Fai (Lake of Young Men and Maidens) and Tiwu Ata Polo (Bewitched or Enchanted Lake) are separated by a shared crater wall and are typically green or red in color, respectively. The lake colors do vary on a periodic basis. Subaqueous fumaroles are the probable cause of active upwelling that occurs at the two eastern lakes.

The lake have been a source of minor phreatic eruptions in historical time. The summit of the compound 1639-m-high Kelimutu volcano is elongated two km in a WNW-ESE direction; the older cones of Kelido and Kelibara are located respectively three km to the north and two km to the south. The scenic lakes are a popular tourist destination. Keli Mutu is also of interest to geologists because the three lakes are different colors yet reside at the crest of the same volcano.

The closest airports are Maumere, and Ende. There are regular flights to Maumere from Bali. The drive from Maumere to Moni, the town at the base of Keli Mutu, takes about 3 hours.

Kelimutu is the name of a long extinct volcano that has become commonly excepted as one the most and if not the most wonderful and fascinating natural sight in the whole Indonesian archipelago. Its distinct feature is the three huge colored lakes at the top. The largest of which is a bright turquoise, a close by green lake and slightly further away a black lake. These wonderful sights owe there interesting colours to chemical reactions that occur in the volcanic craters and more interestingly these colours change throughout time and even on a periodic fluctuation basis, only 30 years ago the green lake was a maroon brown colour.
