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. 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.
