River
Since Bangladesh is a riverine country, river transport is the most popular and common mode of transport. The navigable waterways vary between 8372 kilometer during the monsoon to 5200 kilometer during the dry season. Inland transport is mainly operated by the Bangladesh Inland Water Transport Corporation (BIWTC), which operates the large car ferries.
There are seasonal difficulties in the navigability of rivers and canals for the traditional country boats that constitute the great bulk of the merchant fleet, but geography and history have made these craft the preferred means of moving goods between the ports on the Bay of Bengal and the interior and between surplus and shortage regions of the country.
No trip in Bangladesh is complete unless you have taken the “Rocket” service from Dhaka to the southern parts of Bangladesh. The vessels running this route are original paddle steamers.
City Transport
Travelling in and around Dhaka isn’t as easy as in other countries if you are expecting to take taxis everywhere. Recently a large number of metered taxis (both with and without A/C) has been introduced in Dhaka. Yellow taxis have airconditioning while black ones do not. Large hotels might have their own fleet, or have a Hertz or other car rental office.
One can try the Baby Taxis, the bone shattering motorized three-wheelers, or the mishuk, a modified motorized version of the ubiquitous Ricksha.
For short trips around town, and if you have plenty of time, I would most wholeheartedly recommend that you try a rickshaw; the human pedaled vehicle is ever present and will take you to most anywhere. It would be unlikely that a rickshA wAlla will speak English, so you will have to be prepared for some interesting bargaining.
