I highly recommend booking your ticket through Sopheak Na Travel agency if you are looking for a trustworthy agent while you’re in Siem Reap. Her services are frequently used and recommended by expats. If you are going down Sivatha road from National 6, turn left where you see ABA Bank and her office will be on the right hand side. Just ask around.
There are three price options (US dollars) to bus to Bangkok:
- $9 to leave at 8:00 a.m. with one transfer at the Poipet border and arrive around 6:00 p.m. in Bangkok
- $13 to leave at 6:00 a.m. with one minivan transfer in Poipet and arrive at 2:30 p.m. in Bangkok
- $25 for a direct bus to Bangkok. I’m not sure what time this bus leaves.
I chose the $13 option because I wanted to arrive in Bangkok early afternoon. We went by minivan the whole way, which is a lot faster than the bus.
Just so you know, there is a 20-minute stop in Kralanh where you can use the bathroom “for free” when you buy a snack.
Some travelers on the same bus look for each other because they’re worried about losing their bus after they cross the border. Before you cross the border, the staff will give you a sticker to put on your shirt so someone can spot you when you have entered Thailand. After you’ve gotten your stamps, just keep walking ahead and someone will spot you and tell you where to wait until everyone on your bus or minivan is ready. Then you will likely take a tuk tuk with the other passengers to the other minivan or bus.
For the $13 option, I was happy that the BTS train station was only a 5-minute walk away from the final stop in Bangkok. So don’t waste your money on a taxi if you can take the BTS train first.
