Kelimutu National Park

Kelimutu National Park is a protected volcanic area in Ende Regency on Flores Island, East Nusa Tenggara, Indonesia. It is centered on Mount Kelimutu, famous for its three summit crater lakes that periodically change color due to volcanic mineral activity. Established as a national park in 1992, it protects montane forest ecosystems and endemic flora and fauna. The park is a major natural attraction known for sunrise views over the lakes and cultural importance to the local Lio people.

Visitors can expect a hike to the summit of Mount Kelimutu (around 1,638-1,690 m elevation) to view three distinct crater lakes - Tiwu Ata Bupu, Tiwu Ko'o Fai Nuwa Muri, and Tiwu Ata Polo - known for their changing colors from turquoise to green, red, and black. The setting is a volcanic mountain with paved stairs, viewing platforms, and a summit monument. Surroundings include montane forest, misty highlands, and the nearby village of Moni. Most visitors arrive before dawn for sunrise over the lakes.
