Georgia's secondary road link with Turkey passes through Akhaltsikhe, and it is fairly easy to catch a marshrutka or hire a taxi going to the Vale-Posof border crossing from Akhaltsikhe's bus station.
There is also a seldom-traveled road heading south from Akhalkalaki through Ninotsminda towards Gyumri, in Northern Armenia. Foreigners traveling this route will give the bored customs officials a big surprise.
