What should a first-time traveler see in Bangladesh beyond the obvious highlights?

Both are made of the same material and tell opposite stories. Bagerhat is a 15th-century Muslim city of mosques and mausolea built on the edge of the Sundarbans delta, close enough to Khulna to pair with a mangrove trip. Paharpur, far to the north in Naogaon, is the excavated ground plan of a Buddhist monastery — a vihara — that predates Bagerhat by centuries. Visiting the two means crossing most of the country, which is itself the argument for not treating Bangladesh as a Dhaka stopover.

Bangladesh's intangible heritage gives a third thread, and it is textile rather than architectural. UNESCO inscribed the traditional art of Jamdani weaving in 2013, through Decision 8.COM 8.4 taken at the Committee's eighth session in Baku, having found that the element satisfied all five Representative List criteria, R.1 to R.5. The Committee also invited Bangladesh to apply the Operational Directives on commercializing intangible heritage, and specifically to ensure that the producers are its principal beneficiaries — which is a useful thing to know before buying a sari. Jamdani is woven around Narayanganj, within reach of Dhaka.

In the Sundarbans itself, the Bangladesh Forest Department's own tourism portal names the places its permitted itineraries actually go: the Herbaria forest office area, the Sundarbans East Wildlife Sanctuary and Katka forest office, Kochikhali's bird island and beach, the Chandpai forest area, and the Karamjal animal breeding center with its turtle and dolphin facilities. Those are the named destinations, and they are what a boat permit covers.

Paharpur reads as foundations rather than architecture — a vast square of brick walls knee- to waist-high around a central mound, in flat farmland that gives you no vantage point except the mound itself.

Sundarbans trips are escorted by law, not by custom. The Forest Department's tourism portal states that an armed forest guard from the Forest Department accompanies the trip and that forest fees and permission are part of what a permitted operator arranges. The same portal imposes night silence from 21:00 to 06:00 on vessels. That is the practical difference between a Bangladeshi Sundarbans trip and a general boat cruise: the rules are the forest's, not the operator's.

• Southwest — Bagerhat and the Sundarbans together, out of Khulna; the 1985 mosque city and the mangrove share one corner of the country.
• North — Paharpur as its own journey, with the brick vihara's footprint best read in low morning light across flat land.
• Around Dhaka — Jamdani weaving villages, where the 2013 inscription is a working industry rather than a display.

Some of Bangladesh's most scenic country is restricted. The US Department of State records that travel to the Chittagong Hill Tracts — Khagrachari, Rangamati and Bandarban districts — requires prior approval from the Ministry of Home Affairs Office of Public Safety, and advises reconsidering travel to Southeast Bangladesh and to Dhaka. The Forest Department's night-silence rule and guard requirement also mean Sundarbans itineraries are fixed rather than flexible once you are aboard.

Pair this with the Bangladesh food and drink question in this guide for what to eat in Khulna and Dhaka, and with the when-to-visit question for the season that makes the delta navigable.
