If you’re in Kars or Ardahan in northeastern Turkey and you want to cross into the neighboring country of Georgia at the Posof border-crossing point, here’s what it’s like, described by TTP user Moritz Gathmann of Berlin, Germany:
Crossing the Turkish-Georgian Border at Posof
You take a minibus from the minibus station in Kars to Posof (4 hours), then a taxi/minibus via Türközü and Eminbey to the border (30 minutes).
The road on the Georgian side is very bad. You have to get a taxi (US$25) that will take you to Akhaltsikhe.
From Akhaltsikhe it’s easy to get to Tbilisi by minibus.
