Vietnam is a long and skinny country. This means that it can take a long time to get from one part of the country to the other. Sure, you can fly, but if you are traveling on a budget, that can get a bit expensive. Vietnam has a good and comprehensive rail network too. But if you want to save money, sooner or later you’ll end up on a Vietnamese sleeper (night bus). We took the sleeper bus from Hanoi to Hue.
