By boat, because there is no road access to the delta at all. Trips leave from Khulna or Mongla and typically run as a two-night, three-day cruise into the mangroves, with the practical visiting window from mid-November to mid-February. Booking through an operator is the norm, and it is worth confirming exactly which forest permits and escorts the package includes rather than assuming. Carry the full itinerary offline: once the boat is inside the delta there is nothing to load it from.

It depends how much of the day you want to spend arriving. Dhaka to Cox's Bazar is about 423 kilometres by road; the direct train covers 551 kilometres of track in roughly eight hours, while the flight takes about an hour. The train is the scenic middle option and the flight is the one that preserves a day at the coast. Whichever you pick, remember the beach itself runs about 120 kilometres, so the transfer from the station or airport to a specific stretch of sand is a separate leg.

Plan two or three fixed points a day rather than a list, because a short hop routinely takes an hour and the map badly understates it. Group things by area — Lalbagh Fort and the old city in one block, Ahsan Manzil and Sadarghat by the river in another — and travel between them at the least congested times you can manage. Airport transfers show the same pattern: allow roughly fifty minutes from Hazrat Shahjalal and considerably more at peak, though a night arrival can do it in twenty-five to thirty-five.

The season is restricted and the rules have changed more than once, so this is a case for checking current sources rather than an older account. What holds is the shape of it: visitor numbers to the coral island are capped, a ticketing and travel-pass system applies, and access runs by boat from the Cox's Bazar area. Confirm the current season, the pass requirement and the sailing before building days around it, and treat any itinerary that assumes open access as provisional.

November to February. It is dry and cooler, overland movement is at its easiest, and it contains the practical Sundarbans window of mid-November to mid-February. The monsoon runs June to October with heavy rain and flooding, and cyclone risk peaks in late April to early June and again in October to November. Those conditions disrupt ferries, boats and intercity roads rather than merely making things wet, so an itinerary in those months needs genuine slack built into it rather than a tight sequence of connections.

Only when India is named on the plan's own destination list. It is the common pairing by a wide margin: Kolkata and West Bengal are reached via the Benapole and Petrapole crossing, and the Indian northeast via Akhaura and Agartala, with flights as the alternative. Nepal and Bhutan are usually added by air from Dhaka or Kolkata rather than overland. At each land crossing the handset leaves one national network for another, so read the coverage list rather than assuming a regional label covers the route.

Use terminal Wi-Fi to check the setup before your onward transfer. Open the guide supplied with your plan, confirm that the Bangladesh profile is enabled and selected for mobile data, then follow its roaming, network-selection and APN steps; restart only where instructed. If you intend to take a train, check the airport’s current shuttle connection to Airport Railway Station and the onward timetable. In the Sundarbans, local service may be unavailable, so download essentials before the boat journey.
