Perhaps easiest of Indonesia's volcanoes to enjoy, the multicolored Kelimutu lakes are a popular stop in Flores. Kelimutu's three crater lakes continuously bubble and boil; the other-worldly colors change periodically as the chemical composition of the noxious water changes.
Local lore holds that spirits of the dead ascend Kelimutu and come to rest in one of the three lakes, depending on their deeds performed on earth.
Kelimutu is located just nine miles from the small, pleasant village of Moni roughly between the towns of Ende and Maumere in Flores. Most visitors grab shared transportation to the volcano around 4 a.m., enjoy sunrise on the summit, then walk or hitch a ride back to Moni.
