The Magnificent Three Color Lakes, Kelimutu.
Kelimutu is one of many nature wonders in Indonesia. The volcano is situated in Koanara Village of Moni, Flores. The volcano has three craters with different colors, hence the Kelimutu's craters known as Three Colors Lake or Danau Tiga Warna.
Some scientists suspect the color change occurs because of volcanic activity, refraction of sunlight, water microbiota, dissolved chemicals, algae, and the reflection color of the walls and bottom of the lake
