St. Martin's Island of Bangladesh

St. Martin's Island is a small island (area only 8 km²) 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. There is a small adjoining island that is separated at high tide, called Chhera island. It is about 8 km west of the northwest coast of Myanmar, at the mouth of the Naf River. 

The first settlement started just 250 years ago by some Arabian sailors who named the island ‘Zajira’. During British occupation the island was named St. Martin Island. The local names of the island are "Narical Gingira", also spelled "Narikel Jinjira/Jinjera", which means 'Coconut Island' in Bengali, and "Daruchini Dip". It is the only coral island in Bangladesh. The only way to reach the place is the water transportation i.e. boats and ships (mostly for tourists) from Teaknaf. Do not expect to find taxis, tarred roads or electricity here in the island. Except for the larger hotels that run on generators, there is no electricity supply from the national grid in the island since a dangerous hurricane in the year 1999. The island is all about sun, sea and palm trees. During the day, the island comes alive with water and beach sports, with beach parties and bonfires lighting up the evening skies. 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 overfished. Every year the fishermen must venture further out to sea to get their catch. Most of them use motorless boats. You will get the best weather usually between November and February. Undoubtedly, this is the major tourist season. Between March and July, a tourist must keep his eyes on the forecast keenly, as a cyclone can strike during these times. The island was devastated by a cyclone in 1991 but has fully recovered, and was untouched by the 2004 tsunami. Thus, March to July is tourist off-season.
