The main river terminal on the Buriganga, where enormous wooden paddle steamers and launches depart for every corner of the Bangladesh river network. Sadarghat is one of the most viscerally impressive scenes in Dhaka: a continuous motion of boats, passengers, porters, food sellers, and hawkers at the edge of a wide, brown, busy river, with the skyline of old Dhaka behind.
Even if you are not taking a river journey, the terminal is worth seeing for the boats and the activity. The best view is from the pedestrian bridge over the terminal or from one of the small tea stalls on the waterfront. Ferries depart overnight for Barisal, Khulna, and Chandpur — a long journey but an experience that few non-Bangladeshi visitors make.
