There is a thrice-daily bus service from Phnom Penh with GST Transport that costs $12 and takes about nine hours. From Siem Reap, Rith Mony buses leave once daily, for $5 and take just over two hours.
GST also runs a service from Anlong Veng to Sra’Aem, from where you can visit Preah Vihear temple.
Both Rith Mony and GST are notoriously unreliable transport companies. Their schedules are liable to change at any time, and with little notice. Also, especially on longer journeys where there may be regular stops, make sure to keep an eye on your bags.
A taxi from Siem Reap to Anlong Veng will cost roughly $45.

Motodops are available in town — near the market on the south road — where you’ll also find the taxis. The town itself is small enough to walk around. For a half-day trip up to the Dangrek escarpment, expect to pay $5 return. Some of the motodops may speak English, though few.
Crossing to Thailand
If you’re crossing the border to Thailand, you can pick up local vans on the other side to take you to Ban Lalom where you can catch connecting buses to Khorat and Ubon Ratchathani.
