Covering roughly nine square kilometres off the north-western coast of Cox's Bazar, Sonadia is a low barrier island divided into sandy dunes on the west and mangrove canals on the east. The beaches are home to colonies of bright red ghost crabs and serve as crucial breeding grounds for olive ridley sea turtles. Winter brings migratory waterfowl, curlews and sandpipers to the tidal flats, making it one of the quietest coastal habitats in Bangladesh.

How to get to Sonadia Island
Take a speedboat from Cox's Bazar to Maheshkhali (20 minutes), then hire a four-wheel auto-rickshaw to Ghotibhanga ghat, followed by an engine boat crossing to Sonadia.
Cox's Bazar town is about 395 km from Dhaka, around 8 hours by road. Every way to get there is in the Cox's Bazar guide.
There are no commercial hotels or restaurants on the island; carry sufficient water and food, and plan to return before late afternoon.
