1. Transportation in Vietnam: DOs & DON’Ts

Planes, Trains & Buses

DO consider flying if you’re going a long way within Vietnam, because any other means of transport is always much slower and sometimes only slightly cheaper.
DON’T get stuck in the mud: in the rainy season, road and rail are frequently flooded or even washed away in the regions that are hardest hit.
DO reconfirm any flight to make sure there’s no change.
DON’T arrive at the airport just in time for a domestic flight. Until recently, it was actually more expensive for foreigners to travel from Hanoi to Hochiminh City by train than by air. And this is for a journey that still takes a couple of days as opposed to a flight lasting a mere couple of hours!
If what you are after is seeing plenty of scenery and having time to meet people and chat with them, DO let the train take the strain. Trains are still very slow, despite reports almost weekly that they are picking up extra speed. They are also a bit noisy and often rather Spartan, but a very pleasant and civilized means of transport, with much more legroom than any kind of bus, and conserve some of the charm of a bygone era. They offer – for a price – air conditioning, plush seats, comfy sleepers and gourmet food in a restaurant car.
DON’T opt for the bus if you’re prone to claustrophobia, motion sickness, are pregnant, suffer from a weak heart or actually expect to have a good time. The Vietnamese are not renowned for the safety or courtesy of their driving.
DO use local city buses: once you’ve worked out where to catch the ones you want, these present an excellent (and stunningly cheap) way of getting around. Cities in Vietnam are investing in new buses and improving the service in an effort to combat traffic congestion.
DO keep things on the planes, trains, and your hired vehicles clean. In case there’s something wrong you may find, call the master right away, or else you may get into trouble later.
