This week we crossed from Thailand into Cambodia at this underused crossing point. We'd been a bit apprehensive because of previous bad reports - but is was quick and easy.
We took one of the scheduled minivans from Surin Town to the border. The journey took about 90 minutes and was comfortable enough. On the Thai side of the border it took five minutes to get our exit stamp in our passports. One guy in our party had lost his Thai entry/exit form and a Thai official charged him 500B for a replacement. We reckon that was a wee scam, as the form is free isn't it? Then a friendly Cambodian civilian offered to show us where to go for cambodian immigration. He wasn't trying to scam us and we only had to wait some ten minutes for our visas to be granted and stuck in our passports. Be aware though that the Cambodian immigration officer asked us to pay in Baht - maybe he can get a small margin in his back pocket? We told him we only had the required $20 and he shrugged his shoulders and it was all ok. We thought we were through and clear, but our friendly Cambodian civilian told us we needed to cross the street and fill out a separate immigration entry/exit form. Again, he wasn't trying to scam us, and we filled out the second form with no fee attached. He then explained that we'd have to take a taxi to Siem Reap as its too far for songthaews. We'd already budgeted for a taxi fare of up to 2500B so when he got us a Toyota Camry for 1600B we were more than happy.
The taxi ride took us 2 and a half hours, including a fuel stop and the driver stopping to buy some fruit to share with us.
All in all a very pleasant experience.
