Three color lake is located in Mount Kelimutu, Flores, NTT. There were three adjacent lakes but with different colors. Crater Lake is Tiwu Ata Polo (red lake), Tiwu Nua Muri Kooh Fai (green lake) and Ata Tiwu Mbupu (blue lake). Lake Flores is the only lake in the world in which the water may change at any time, from red to dark green and maroon, dark green to light green, dark brown to blue sky. This natural phenomenon is a miracle.
