The only coral island of the country that started forming at least since the last maximum glacial age (ca 40,000 years ago)!

It`s a small island in the northeast 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 island is 7.315 km long. Geographically, it is divided into three parts. The northern part is called Narikel Jinjira or Uttarpara and is 2,134m long and 1,402m wide. The southern part is known as Dakshinpara, which is 1,929m long, with a narrow tail of 1,890m towards the southeast, and a maximum width of 975m. A narrow central belt or Maddhyapara connects the two parts. The length and the width of this belt are about 1,524m and 518m respectively and the narrowest collar is known as Golachipa. In addition to the main island there are a number of tiny islets ranging from 100 to 500 sq m which are locally known as Chheradia or Siradia which means separated island. There is a shallow lagoon in the middle of Uttarpara and it is connected to the sea during high tide by a narrow channel on the western coast. The topsoil of Uttarpara consists of alluvial sands mixed with shells of molluscs. There are two small dead lagoons and a stretch of marshy land in Dakshinpara. Fish landing sites, bazars and schools are present only in Uttarpara.

The population is about 3,700 and most of them are fishermen belonging to 535 families. One hundred eighty-two species of wildlife are recorded from the island. Of these, 4 species are amphibians, 28 reptiles, 130 birds and 20 mammals.

St. martin`s main vegetation is coconut, betel nut and bamboo. Coconut trees are abundant and more concentrated in the Jinjira area. The soil of the island is not so fertile. The main agricultural products are onion, watermelon and some rice.
Ho to get there:
Getting to St. Martin''s is a three-step program. First you''ll need to fly or bus it down to Cox's Bazar, and then catch a bus or micro bus to Teknaf, which is right on the very tip of Bangladesh, sandwiched up against Myanmar.
I prefer micro buses but make sure u booked 2 seat for you in microbus. From Teknaf, local boeats run daily to St. Martin Island.On turism season(November to February) you can find comfortable ship in Teknaf port.
The total distance from Dhaka to the island is 510km (316mi).
November to February is the perfect time for St. Martin.
