The province of Pailin is a former Khmer Rouge stronghold, now a backwater border town. Historically a gem town, Pailin has attracted immigrants from gem-packed Burma, which gives it a unique culture that is neither strictly traditional Khmer nor Burmese.
Pailin is 80km from Battambang on National Highway 57. The highway was resurfaced in 2011, making for easy access, even during the wet season. A couple of bus companies run a service from Battambang to Pailin, costing between $3 and $5 a ticket, and taking roughly 2 hours.
A small town, Pailin is easily covered on foot. Motodops will give a lift anywhere in town for about 1,000 riel and will drive to the Thai (16 km by road) border for about $3-5.
There is a Burmese-style stupa built by Shan immigrants in 1922, Wat Phnom Yat.
