What is the cheapest way from Bangkok to Chiang Mai?

The bus is usually cheapest, with VIP coaches from roughly EUR 18 to 28. The overnight train costs a little more and saves a hotel night, so it is often the best overall value.

Is the overnight train worth it?

For many travelers, yes. You leave Bangkok in the evening, sleep in a berth, and arrive in the morning, which removes a hotel night and a travel day from your trip.

How long is the flight?

About 1 hour 20 minutes gate to gate, plus airport time. It is the fastest option and fares are competitive when booked ahead.

Do I need to book the sleeper train in advance?

Yes. Second-class air-conditioned berths sell out days ahead in high season, so book early.
