Out with its cities Bangladesh is a country of vast natural beauty. To the far south east lies Cox Bazar, the longest unbroken sea beach in the world, boasting pristine sandy beaches, coconut palms and tropical climates. On the opposite coast bordering India's West Bengal lies the Sundarbans ('beautiful forests') which is the largest single mangrove forest in the world.
The third reason is for the pictures! When you travel the world you will get soooo many picture opportunities that you will go crazy, from happiness. Then you can come back and share all of your awesome experiences with your friends and family.
Shahjalal International Airport in Dhaka is the principal gateway to the country if you are arriving by air.
When you can, take a bus or train: When it comes to budget traveling, this is the way. Night buses get you from one country to the next for next to nothing, although they do take longer, no doubt about that. Roads between many destinations are well enough to travel, although there are going to be bumpy rides. None the less, when you need to do it on the cheap, this is the best option.
