The Semporna region is the diving and snokelling paradise of Sabah. At this vicinity there are two marine parks, including the world-famous Sipadan Island Park and Tun Sakaran Marine Park which have a very high level of marine diversity. Both Parks were established about the same time in 2004. Sipadan the only oceanic island in Malaysia, attract scuba divers from all over the world. Reef Sharks, Hammer Head Sharks, Barracudas, Sea Turtles, and host of fishes are what made the divers come back for more. The Semporna Islands Park, which is another name for Tun Sakaran Park, is formed by eight islands and three reefs. Hard and soft Corals, with a wide varieties of reef fishes like, Anemonefish, Angelfish, Butterflyfish, Cardinalfish, Damselfish, Surgeonfish, and Wrasse are found here.
For much of the history of the Semporna region on the south-eastern part of Sabah, this region consists of a sleepy town and a few villages with the main occupation being fishermen. This is not the case any more, since the last two decades this region has become the underwater paradise for the state. To protect the marine diversity of this region, Tun Sakaran Marine Park was established in 2004 and managed by the Sabah Parks. This Marine Park has eight islands as well as three large reefs and the park is surrounded by the Celebes Sea. Because of its proximity to the world’s reknown Sipadan Island Park, divers, snorkellers and tourists are also taking time to visit this park. If one comes from the Semporna Jetty, this would take about 30 to 45 minutes and covering a distance of 15 to 25 kilometres, depending of which island is the destination.
