Bangladesh is built on the delta of the Ganges and Brahmaputra, and water shapes almost everything: the Sundarbans mangrove forest in the south, river ferries as everyday transport, and Cox's Bazar with one of the longest natural beaches in the world.
The guides on this page cover Bangladesh as a whole. The monsoon from June to October brings flooding that affects large parts of the country, which makes the dry months from November to March the practical season. Dhaka is among the most densely populated cities anywhere and traffic there is a genuine planning constraint. Sundarbans trips are normally arranged as multi-day boat tours through operators.
