Lakes of Mount Kelimutu, Indonesia
The three crater lakes of Mount Kelimutu on Indonesia's Flores Island are a haunting—and possibly haunted—sight. Considered to be the resting place for departed souls, the lakes are locally referred to as "the lake of old people," "the lake of young men and maidens," and "the lake of evil spirits." Bizarrely, all three lakes change color dramatically and unpredictably, from blue or green to black or red. Reaching the popular sight requires a long drive on a steep and winding road.
