Begin with Hue’s palace courtyards and royal tomb landscape, cross the Hai Van coast by train, then spend time with Cham sculpture in Da Nang and the merchant streets of Hoi An. The railway is an outing in its own right, while the short final road move leaves an evening to get to know the old town. This route suits someone who enjoys history, food and walking but also wants a less formal coastal afternoon.
Sleep in Hue after days one and two, Da Nang after days three and four, and Hoi An after days five and six. Days two, four and six are the full sightseeing days. The other days include arrival, hotel changes and the airport departure. Keep the Hoi An cooking programme as an alternative to the fuller heritage day; that choice leaves time to eat lunch properly and return to your room.
March and April are useful months to compare for all three bases: Hue’s spring and Da Nang’s drier season overlap, before the strongest summer heat. Later in the year, central Vietnam can have heavy rain and flooding, especially around Hue. Pack walking shoes and light rain protection, and use the indoor alternatives described below if conditions change.
