Inter-region transport: trains and buses
The **State Railway of Thailand** runs long-distance lines from Bangkok north to Chiang Mai, northeast to Isaan, and south toward the Malaysian border; overnight sleeper trains are a comfortable, scenic option, with second-class air-con sleepers popular among travellers. Long-distance **VIP and air-con buses** reach almost everywhere, are inexpensive, and often run overnight. For islands like Koh Samui, combined bus-and-ferry or train-and-ferry tickets are sold as a single through-fare. Government buses leave from official terminals; be wary of cheap 'tourist' minibuses with poor safety records.
