Dhaka is the capital of Bangladesh, home to the historic Lalbagh Fort and the Baitul Mukarram mosque. The city is also known for its countless rickshaws.
Dhaka is a capital you cannot "see" at a gallop: the city swallows you whole into a current of rickshaws, horns and human noise. There are almost no foreigners here, which means you will be looked at with genuine curiosity rather than as a walking wallet — a rare feeling in South Asia.
Dhaka is not about pretty postcards but about immersion. People come for a living, unretouched metropolis, for the Sundarbans within reach, and for the sense of a place mass tourism has not yet found. The essential thing is to accept the chaos in advance: traffic eats hours, there are barely any pavements, and the air is dusty. If that irritates you, two days will be plenty. If it excites you, you will fall for the place.
In two days you can realistically cover Old Dhaka (Lalbagh Fort, Ahsan Manzil, the Star Mosque, Sadarghat) in one and the modern central districts in the other. For the Sundarbans, set aside two or three days of their own; there is no sense in rushing it.
Bara Katra and Chhota Katra are badly decayed — go in only if you are already nearby and like ruins.
Hazrat Shahjalal Airport (DAC) is in the north of the city. Because of traffic the drive to the centre can take anything from an hour upwards — leave a buffer, especially for the flight home. Use Uber or the local equivalent Pathao through the app: that avoids the haggling and the foreigner's price.
Within the city:
The main trick: plan your day by geography, not by wishes. One crossing of the city at rush hour will kill half of it.
Bengali cooking is underrated and very good. Do try biryani (kacchi, with mutton), hilsa fish, and for dessert mishti doi (thick sweet yoghurt in a clay pot) and roshogolla. Eat at local places, known as "hotels" — cheap, filling and authentic: a full lunch comes to a few dollars. Tea in a glass costs almost nothing; take one on every corner.
Prices feel very low even by Asian standards. Only the Western restaurants and hotels of Gulshan get expensive.
Dhaka is safer than the chaos suggests: violent crime against visitors is rare. The real risks are traffic (cross the road with great care, vehicles do not give way), pickpockets in crowds and small-scale overcharging. Friday is the day off and much runs differently. Dress modestly, especially near mosques. Drink only bottled water, and approach street food cautiously on the first day.
