Sg Golok's raison d'etre is to serve sex tourists. It's the quintessential cowboy town where mini-skirted girls race around town in Kap-chais and nobody even pretends to sing in karaoke bars fronting for brothels. A 'friend' - yes, we all have one of these well-informed friends - say Sg Golok is the finishing school for Thailand's sex industry. Once you've made it here, you 'graduate' to Hat Yai and subsequently to major tourist hotspots like Bangkok, Pattaya, and Phuket. If not, you go to Betong.
