is quite easy by bus, air, train, or car. Thai Air has 4 to 5 flights daily to and from Bangkok (check Thai Airways schedules here). If you have the time to take the train, some of the sights will be quite spectacular and some quite monotonous, but you will be traveling with the local population. The bus is more convenient for the shorter trips, while it is much cheaper it sometimes appears the driver has no concern for anyone's safety (including their own).
