Voio is the westernmost and most beautiful part of the Kozani District, and remains unknown to the wide public. The landscape is dominated by two large mountains orientated to the north and to the south and water. The largest river of Greece, Aliakmonas, separates it into western Voio, where mount Voio is located (alt. 1812 m), characterized as an Area of Outstanding Natural Beauty, with many Wildlife Resorts and Eastern Voio, which is essentially the area of mount Askio (alt. 2111 m), characterized as Natura 2000. River Aliakmonas springs from the west, as well as its largest influents, Pramoritsa, Velos, Stravopotamos and the northern streams of Venetikos. From the basin shaped by mount Voio, Smolikas and Grammos, river Sarantaporos also springs, which ends up in Aoos.

The area’s history as well as its name go back to antiquity. Ancient Greek geographers , such as Strabo, would use the name Voio for the entire mountain range of Pindos. It is mentioned that Voio is a long mountain that marks the border of the land of Aitolia. Centuries later, when European explorers were travelling and mapping the a Greece unknown, obscure and conquered by the Ottomans, they mention that Voio made a special impression on them, due to the number and peculiarity of its peaks.

This is where the vast mountain chains and proud stony villages begin, with their unique nature, traditions and architecture. Whatever meets the eyes in these spectacular highlands is included within Voio. Untrodden peaks, waterfalls, canyons, precipitous rocks, enormous atmospheric forests teeming with life, legends and buildings of days of yore, caves, lakes, winding rivers and steep streams, stone bridges and hidden paths characterize this blessed land. The rich mountainous ecosystems are dominated by deciduous and conifer and mixed forests, where one can find biotopes of every kind of flora and fauna characteristic of Northern Greece.
