Bordered by India and Myanmar, Bangladesh is the most densely populated country in the world. The main cities of Dhaka and Chittagong certainly reflect that, but there is beauty in the chaos. Outside of the main cities, there is also surprising contrast, from the green tea plantations of Srimangal and largest mangrove forest in the world in the Sundarbans. My favorite places, however, are the varied tribal regions of the Chittagong Hill Tracts with 14 ethnic minorities.
