Flores is one of the Lesser Sunda Islands, an island arc with an estimated area of 14,300 km² extending east from the Java island of Indonesia. The population was 1,831,000 in the 2010 census and the largest town is Maumere. Flores is Portuguese (as well as Spanish) for “flowers”.
Flores is located east of Sumbawa and Komodo and west of Lembata and the Alor Archipelago. To the southeast is Timor. To the south, across the Sumba strait, is Sumba and to the north, beyond the Flores Sea, is Sulawesi.
The most famous tourist attraction in Flores is Kelimutu, 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 fed by a volcanic gas source, resulting in 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.
