In a past piece we presented the most treacherous roads in the world, one of which was in Greece. The Perdikaki-Patiopoulo mountain road, located in the region of Aetolia and Acarnania, in western Greece measures 23,5 km in length and is considered the most dangerous in Greece. This road has some very challenging twists and turns and consists of either steep climbs or dangerous descents, with little road grip to speak of. We do not recommend you attempt this road if you are visiting Greece. Its not a fun drive to say the least. Watch a driver driving along the road in the following video.
