Trains
The train is a large reason for Hat Yai's being. The city is where the two lines running up either coast of Malaysia come together. So, you can reach Hat Yai by Train from Singapore via either Kuala Lumpur and Butterworth or through Kota Baru; or you can come from Bangkok in the north down to Hat Yai.
Buses
Like the rest of Thailand, inter-city buses are available between Hat Yai and most anywhere else. Your choices are both air conditioned and non-air conditioned buses. You can also travel from Singapore, Kuala Lumpur and Penang to Hat Yai by bus.
