The deep south's cheapest arrival. Booked a few weeks out this often costs less than the sleeper berth and saves the fifteen hours.

Sleeper train · 14h30–16h · ฿738–฿938

Trains 31/32 use the newer Chinese-built sleeping cars and cost about ฿100 more than 35/36; 1st class runs ฿1,146–1,546. Fifteen hours is a long night — this is the leg where 1st class earns its money.

Both ends of the trip

Bangkok

The arrival point for most trips and the hub every rail and bus line runs back to.

Airport BKK / DMK: Two airports 50km apart on opposite sides of the city; a domestic connection between them needs 3 hours, not 1.

Bangkok is driest Nov–Apr and wettest May–Oct on its own monthly rain-day normals.

Going the other way, or further

The return trip is on the Hat Yai to Bangkok page — fares are the same in both directions on almost every leg here, but the timetables are not. To string this hop into a longer trip with a pace check, use the route planner, and see the island comparison for which coast is dry in the month you are travelling.

The Bangkok end of this leg starts at a station or a terminal rather than a hotel door: getting around Bangkok has the BTS, MRT and boat fares for reaching Hua Lamphong, Krung Thep Aphiwat and the two bus terminals, and airport to city covers the Suvarnabhumi and Don Mueang runs if the leg is a flight.
