The province of Pailin is a former Khmer Rouge stronghold, now a backwater border town.
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.
