Jambudwip is a forested island in the Bay of Bengal about 8 km southwest of Bakkhali and Fraserganj, accessible by motor launch from the Fraserganj jetty. The crossing takes roughly thirty to forty minutes and crosses open water, giving views of the estuary mouth and occasionally of dolphins. Permission is required from the Forest Department to visit — this can usually be arranged through operators in Bakkhali or Fraserganj.
The island itself is dense mangrove forest with no permanent inhabitants and no facilities. The attraction is the forest walk on the established paths, the birdlife (including herons, kingfishers, and egrets), and the simple fact of being on a wild island at the edge of the Sundarbans. Spotted deer are present. Tigers, though theoretically possible given the Sundarbans connection, are not a realistic concern on Jambudwip. Plan the excursion as a half-day from Bakkhali.
