I'm in Thailand right now. My original plans were to go to Laos and/or Cambodia, but now these plans have changed and I'll only visit Thailand. I need to do a visa run as explained here and the only country I can visit without paying a visa fee or an expensive air ticket is Malaysia.
According to my plans I'll visit Krabi, so the question is, from Krabi, what's the easiest Malaysian border I can access to do a visa run?
