Epirus is a geographical department and administrative region (periphery) in northwestern Greece. It borders the peripheries of West Macedonia and Thessaly to the east, West Greece to the south, the Ionian Sea and the Ionian Islands to the west and the country of Albania to the north. The province has an area of about 9,200 km² (3,551 square miles).
Epirus is rugged and mountainous. It comprises the land of the ancient Molossians and Thesprotians and a small part of the land of the Chaonians. It is largely made up of mountainous ridges, part of the Dinaric Alps. The periphery’s highest spot is on Mount Smolikas, at an altitude of 2.637 metres above sea level. In the east, the Pindus Mountains that form the spine of mainland Greece separate Epirus from Macedonia and Thessaly. Most of Epirus lies on the windward side of the Pindus. The winds from the Ionian Sea offer the region more rainfall than any other part of Greece. The Vikos-Aoos and Pindus National Parks are situated in the Ioannina Prefecture of the periphery. Both areas have imposing landscapes of dazzling beauty as well as a wide range of fauna and flora. The climate of Epirus is mainly alpine. The vegetation is made up mainly of coniferous species. The animal life is especially rich in this area and includes, among other species, bears, wolves, foxes, deer and lynxes.
Epirus is divided into four peripheral units which are further subdivided into municipalities. The peripheral units are Thesprotia, Ioannina, Arta and Preveza.
