To Malaysia
The "Harmony Bridge" across the Golok River connects Sungai Kolok with the Malaysian town of Rantau Panjang. The Thai border checkpoint is about 1km from the railway station; a motorcycle taxi should cost 20 baht. The Malaysian immigration checkpoint is just across the bridge and can be easily walked. Once in Malaysia, you can either catch a bus or taxi to Kota Bharu or Pasir Mas where you can catch trains to Kuala Lumpur or Singapore. See the Rantau Panjang article for more details.

There are two departures daily to Bangkok, at 11:30 rapid and 14:20 express, both stopping at Yala, Hat Yai, Surat Thani and many other towns en route.
