Khulna is about 333 Km away from the capital city, so usually takes 6-7 traveling hours to reach your destination. Roads are free and you will get an interesting motion picture of traditional Bangladeshi standard of living. There are Non AC, AC Economy and Executive bus services from Dhaka to Khulna, serving many private companies along with the Government BRTC bus service. So hop in one of them, they are leaving Dhaka in every half an hour, from early morning to midnight.
We also arrange bus tickets for tourists along with our tour package.
