Just after the Bridge, Immigration couter is in the building on the right. You can just walk straight without entering the building.
Sungai Kolok ( สุไหงโก-ลก) used to be famous with tourists from neighbouring country, Malaysia. However since the rise of the seperatist groups in Southern Thailand where there were shootings, bombings etc few years ago, the town slowly turns to be a very quiet town.
On the way into the town from the border.
Normally on weekends, it might be very difficult to find a hotel room in this border town. However now, it is very easy and you might be given discount for weekends. The border security in Sungai Kolok is not that tight. The Sungai Kolok – Rantau Panjang Bridge connects Thailand and Malaysia.
Vendors from both countries use the bridge a lot. However, the checkpoint in Malaysia is very strict. You need to pass the immigration counter so that your passport or border pass will be stamped. However, after walking across the bridge, you can just walk straight without ignoring the Thai Immigration counter which is situated on the right hand side.
There are plenty of motorcycle taxis around that area. They charge around 20 Baht from the border into the town which is about 1km. Holding 2 nationalities is very comfortable for me to walk in and out between these two countries.
Very quiet even on the day time.
Sungai Kolok is like other Thai border towns. There are Thai, Thai Chinese and Thai Muslim all over. There are also army in almost every parts of the town. For me, without those bombings or shootings, Sungai Kolok is a very perfect town. Not so big or small. Just nice. In Sungai Kolok, the locals speak Yawi, one of the dialect in Malay Language. Thai is being use in the town as well. Some of the Chinese families in the town speak perfect Chinese language.
On the Malaysian side. The immigration counter is in the building which everyone has to go through. It is a little strict than the Thai.
