The Vardousia mountain range is divided into 3 groups according to their peak arrangement, the highest being Mt Korakas at 2495m. The northern group has the smoothest relief, while the southern and western consist of abrupt crests and saddles. In the northern part flysch dominates in the lower parts and limestone in the higher areas. In the south concrete limestone dominates. These factors result in the formation of an extended plateau, especially in the northern part, while steep slopes and conglomerates occur in the south. The presence of flysch contributes to the creation of many torrents and streams. The vegetation is dominated by Abies cephalonica and in some areas Abies borisii regis. Above the forests extensive grazing land occurs, together with well adapted plant associations on the rockier parts.
