Sungai Kolok (สุไหงโกลก) is a border town in Narathiwat, Thailand, just north of the Malaysian border. The town on the Malaysian side of the border is Rantau Panjang which is in the state of Kelantan. Sungai Kolok is popular among Malaysians for its shopping and infamous entertainment delights. Tourism however has taken a knocking since 2005 as several bombs, blamed on southern Thai Muslim separatists, have rocked the town. Sungai Kolok is the railhead on the east coast branch of the State Railways of Thailand's southern line. 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.
