Bavet 2 is the border town between Vietnam and Cambodia. We travelled across the border on a coach run by Sapaco. The process was very easy as the official on the coach took your passport and $25 if you didn’t have a visa for entry to Cambodia (we already had our visa from the Cambodian embassy in London). When you got to the border you went into the waiting room and waited for your name to be called out. When your name is called you go to the desk and get your passport back. We didn’t have to take our luggage off the coach so the process was quite quick.
The coach picked us up from our hotel but it also leaves from the bus station.
