Saint Martin’s is a small beautiful island in the northeastern part of the Bay of Bengal, about 9 km south of the tip of the Cox's Bazar-Teknaf peninsula, and forming the southernmost part of Bangladesh. It is about 8 km west of the northwest coast of Myanmar, at the mouth of the Naf River. The local name of the island is "Narical Gingira", also spelled "Narikel Jinjira/Jinjera", means 'Coconut Island' in Bengali. It is the only coral island in Bangladesh
TourismSt. Martin's Island has become a popular tourist spot. Currently, five shipping liners run daily trips to the island, including Shahid Sher Niabat, L T Kutubdia, Eagle, Keary Cruise & Dine and Keary-Sindbad. Tourists can book their trip either from Chittagong or from Cox's Bazar. The surrounding coral reef of the island has an extension named Chera Dwip. A small bush is there, which is the only green part of Chera Dwip, enhancing the beauty of this island. People do not live on this part of the island, so it is advisable for the tourists to go there early and come back by afternoon.
In the past 5 years St. Martin's visitor population has increased dramatically. While this situation has proven to be lucrative for the islanders, it is causing the natural beauty of the island to deteriorate. Presently there are many efforts being put forth to preserve the several endangered species of turtles that nest on the island, as well as the corals, some of which are found only on Narikel Jinjera. Pieces of the coral reef are being removed in order to be sold to tourists. Nesting turtles are sometimes taken for food, and their hatchlings are often distracted by the twinkling lights along the beach. Species of fish, a few just recently discovered, are being over fished. Every year the fishermen must venture further out to sea to get their catch. Most of them use motor less boats.
