Located close to Cox’s Bazar and the Bay of Bengal, Saint Martin’s Island is a small and very popular island, frequented by tourists from all around the world. The island is tiny and can be explored within a day. No vehicles are allowed on the island either, making it a pollution-free territory. St. Martin’s has an extension called the Chhera Dweep or Chhera Island, that you can visit via a rented speedboat. When not roaming around the awe and beauty of the island, you can try your hand at plenty of activities, such as scuba diving, cycling, and stargazing (or moon gazing if you visit during a full moon). The island also has unique snacks and foods that you do not want to miss!
