Saint Martin’s Island, locally known as Narikel Jinjira, is Bangladesh’s only coral island, a small stretch of coastline in the Bay of Bengal near the southern tip of the country. It’s reachable by boat from Teknaf, with the crossing itself part of the experience.
Expect clear water, quiet beaches, and fresh seafood rather than resorts and nightlife — this is a trip for travellers who want to slow down for a few days.
