Explore Flores island for Kelimutu lake, a volcano containing three colored lakes, located in the district of Ende close to the town of Moni. These crater lakes are in the caldera of a volcano and have highly acidic water. The colored lakes change colors on an irregular basis, depending on the oxidation state of the lake from bright red through green and blue. Labuanbajo (on the western tip of Flores) is a town often used by tourists as a base to visit Komodo islands for liveaboard adventure . Labuanbajo also attracts scuba divers, as whale sharks inhabit the waters around Labuanbajo.
The west coast of Flores is one of the few places, aside from the island of Komodo itself, where the Komodo dragon can be found in the wild and is part of the Komodo National Park, a UNESCO heritage site. In September 2004, at Liang Bua cave in western Flores, paleoanthropologists discovered small skeletons that they described as a previously unknown hominid species, Homo floresiensis. They are informally named hobbits and appear to have stood about 1 m (3.3 ft) tall. The excavation site can be visited as a side trip when touring the island.
