Saint Martin's Island is a small island in the northeastern part of the Bay of Bengal, about 9 kilometers south of the tip of the Cox's Bazar-Teknaf peninsula in Bangladesh. It's the only coral island in the country, characterized by its crystal-clear water, coral pebbles, abundant marine life, and laid-back lifestyle. Measuring only about 8 square kilometers, it offers visitors a unique glimpse of Bangladeshi island life. The local community is mainly dependent on fishing and tourism. The island is separated from the mainland by a channel and can be accessed by boat. The beauty of the island is unspoiled, with coconut palms swaying over pristine beaches. Tourists can experience the simplicity of island life, enjoy the fresh seafood, take part in snorkeling to discover the colorful corals, or simply relax on the beach. It has a small range of accommodations for visitors looking to stay overnight. Due to its ecological importance, the government has declared it an Ecologically Critical Area (ECA).
