In the southeast corner of the park, the island of Rinca has a number of spectacular dive sites. The cold, rich upwellings mean the visibility can be poor, but these same upwellings provide perfect conditions for a wealth of filter-feeding invertebrates. At sites like 'Cannibal Rock' in Horseshoe Bay, the reef is carpeted in crinoids, sponges, seasquirts and both hard and soft corals, and plenty of unusual macro- subjects can easily be found here.
Over in the southwest, the liveaboard boats come in search of much larger animals. At ‘Manta Alley’ currents are pushed between Komodo and a small, rocky outcrop. The plankton that blooms when the cold upwellings hit the sunlit shallows is funneled and concentrated through this channel – perfect feeding conditions for huge manta rays. When the currents are running, large groups of these incredible animals can be observed as they feed, barrel-rolling and spinning only meters away from divers.
Komodo is not without its problems. Illegal and destructive fishing have taken their toll on the reefs and fish life and the sheer volume of tourists visiting some of the more popular sites has also had a detrimental effect in the past. However, the Komodo National Park still remains one of Indonesia’s most spectacular destinations. There are few places where divers can actually get a sense of Indonesia’s geographical position, perched on the edge of the deep Indian Ocean, and how powerful and extraordinarily rich these oceanic waters can be.
