Komodo Island Tours
Exploring Rinca, Komodo, Bidadari and Bat Island
Komodo Island Tours
These islands are composed of a silica-rich rock called rhyolite porphyry. The rhyolite contains large, perfect doubly terminated quartz crystals (lacking the prism faces), some of which are up to a centimeter long. The rhyolite is also rich in magnetite, which weathers out of the rock to form magnetite-rich sand on some of the beaches. In places, silica-rich groundwater has replaced the bedrock with chert. On Rinca, one can see fragments of worked chert lying around near the outcrops. These rocks are geologically distinct from the rocks found on islands to the east and west, which are more mafic in character.
Kelimutu Lake and Mountain
The most famous tourist attraction in Flores is Kelimutu; three colored lakes in Ende district. These colored lakes change colors on a regular basis. The latest colors (late 2004) were said to be turquoise, brown and black. Kelimutu is a small but well-known Indonesian volcano in central Flores Island with three summit crater lakes of varying colors. The western lake, Tiwi Ata Mbupu (Lake of Old People) is commonly blue.
