Komodo is the largest of a group of around 90 islands in the sea between Sumbawa and Flores. While Komodo is famous for its "dragons" - the world's largest lizards - it's also one of the world's premier diving areas. The waters here are rich in diverse marine life, and many of the reefs are untouched by the ravages of over-fishing.
One of the reasons that Komodo remains such a great dive destination is that it is still relatively remote. It's really only accessible by live-aboard cruise. Boats departing from Labuan Bajo on Flores take about two hours to reach the dive area, while boats from Bali take more than a day to reach the western edge of the national park, but also give you the chance to dive some really fantastic sites around Sumbawa Island, to the west of the park.
While the diving is great, it also can be very challenging. The currents around many of the dive sites can be quite strong, and every year one or two divers get swept away. Most of them eventually turn up alive on one of the deserted beaches.
One of the challenges of documenting Komodo's dive sites is that many of the sites have no common name. Each dive operator might have their own name for a particular spot. Also, many of the small islands have several good sites around them. I've tried to document as many as I could, and research the most common names for the sites.
The waters around Komodo Island are part of a national park, and require the payment of entrance and usage fees. The amount of fees depends on the length of stay. Expect to pay around US$75 for a typical five or six day dive cruise.
