Kelimutu, Flores, Indonesia

You might have seen lakes with some unique colours before, but the Indonesian island of Flores, with its volcano Kelimutu, may steal the show. Home to three lakes, each with its own hue and folklore, this natural wonder attracts travellers seeking an otherworldly experience. Volcanic vents deep within the Earth release steam and gas, which alter the lakes' mineral compositions, causing reactions that transform their appearance periodically.

Each lake at Kelimutu has its own unique chemical makeup, which is why they can be different colours from each other at the same time, and these colours can change independently. The westernmost lake, Tiwu Ata Bupu (Lake of Old People), normally has a blue hue. Meanwhile, Tiwu Ko'o Fai Nuwa Muri (Lake of Young Men and Maidens) tends to be green, and Tiwu Ata Polo (Bewitched or Enchanted Lake) is usually red. The local Lio people revere these lakes, believing them to be the resting place of souls. So, why settle for the usual beachside vacation when you can explore a trio of colour-changing lakes?
