Rith Mony has morning buses that originate in Psar Pruhm at the Thai border around 7.30am, pick up passengers in Pailin around 8am, and continue to Phnom Penh (38,000r, eight hours) via Battambang (15,000r, 1½ hours).
Car & Motorcyle
A rough track goes from Treng District, about 25km east of Pailin, southward through the Cardamom Mountains to Koh Kong via Samlaut and Pramoay.
Share taxis to Battambang (20,000r, one hour) leave from the taxi stand opposite Psar Pailin on NH57.
Getting to Thailand: Pailin to Chanthaburi
Getting to the border The laid-back Psar Pruhm/Ban Pakard border crossing (6.30am to 8pm) is 102km southwest of Battambang and 18km northwest of Pailin via good sealed roads.
First get to Pailin from Battambang. In Pailin, patient travellers might get a share taxi (6000r) to the border. If nothing is going, take a moto (US$5) or private taxi (US$10).
At the border Formalities are straightforward and quick on both sides. Immigration officials usually quote US$35 for Cambodian tourist visas here. Ignore all offers from touts on the Thai side to help with visas.
Moving on On the Thai side, you can avoid being overcharged for transport to Chanthaburi (150B, 1½ hours, 10am, 11am, 6.30pm) by hopping on a moto (50B) to the nearby sŏrngtăaou (pick-up truck) station. From Chanthaburi's bus station there are frequent buses to Bangkok (200B, four hours).
