Phnom Penh to Banlung
There are several Bus companies going from Phnom Penh to Ratanakiri Province. To take a big bus in the morning around 7 will take you around 10-12 hours to Banlung. You arrive at the Bus Station out of town, where TukTuks wait to bring you the 3 km to Banlung.
An alternative are the small minivan and private buses that go the way every day. They are usually very crowded but much faster (7-8 hrs). Now there are also VIP minivans availabel where you definietly have your own seat.
Siem Reap to Banlung
The Street from Siem Reap to Banlung is in a very good condition and with the building of the new Mekong bridge in Stung Treng you
just take around 6-7 hours. None of the big bus companies drive on this route. But there are private taxis available.
Laos to Banlung
From Laos you can either take the big bus until Stung Treng and change to a Minivan there or ask for Private Taxi.
