This volcano is best known for the tri-coloured lakes perched on top of it, collectively named Kelimutu Lake. Located at a height of 1,639m (5,377ft), these mystical, colour-changing lakes boast a sweeping mountaintop vista. They also display their own enchanting hues, which have turned from calming turquoise to pitch black over the years. The hiking trail to Mount Kelimutu’s peak is a convenient stairway, although it’s still a bit demanding due to the elevation. The gate opens at 4.30am, the best time to start hiking in order to catch the gleaming sunrise.
