Dhaka is located in central Bangladesh along the Buriganga River. Not only is it the capital city, but it is also the largest in the country. It is the centre of political, cultural, and economic life in Bangladesh. The official language is Bengali, while English is the working language of UN Agencies. In recent decades, Dhaka has seen the modernization of services, communications, and public works. The city is attracting large foreign investments and greater volumes of commerce and trade. It is also experiencing an increasing influx of people from across the nation; this has reportedly made Dhaka one of the fastest-growing cities in the world. Dhaka is connected to other cities by rail, road, and by air and internationals can move easily from one city to another.

Dhaka has venerable green spaces, including many gardens and parks, historical places, and nice restaurants. The weather is tropical - hot and very humid during the summer monsoon season (April-September) and drier and cooler in the winter (October-March). Historically, Bangladesh has been a safe country for internationals so far. While Dhaka is not categorized as a hardship station, the volunteer should be prepared for limitations in freedom of movement on foot, by public transport, and to certain locations.
