Which should you book?

Fly if you have two weeks for the whole country. Take the train if you want the coast overnight and can spare the next morning.

Hanoi to Hue

Fly if the date matters. Take the sleeper train if the journey is part of the trip. The bus is the budget overnight and the least comfortable of the three.

Ways to go

Mode	Time	Notes
Flight	About 1 hour 20 minutes in the air	Plus airport rides at both ends. The practical choice on a 14-day trip.
Train	About 13–15 hours	Reunification Express sleepers. Book a berth, not a hard seat.
Sleeper bus	About 12–14 hours	Cheaper than the train berth and more tiring.
