This tour isn't for you, if you like fancy, touristy places.
But, if you really want to see something different, rainbow mountains, cave monasteries, industrial town, abandoned zoo and ruins, if little offroad is enjoyable, if you want to feel Georgia's old history or soviet stories, or/and if you are photographer or you like to take pictures, this tour is must do thing for you.
P.S. don't forget about wine tastings as well.
