is a region and a municipality in the Pindus mountains in Epirus, in northwestern Greece. The seat of the municipality is the village Asprangeloi. It has an area of some 1,000 square kilometers and contains 46 villages known as Zagori villages (or Zagorochoria or Zagorohoria), and is in the shape of an upturned equilateral triangle. Ioannina, the provincial capital, is at the southern point of the triangle, while the south-western side is formed by Mount Mitsikeli. The Aoos river running north of Mt Tymphe forms the northern boundary, while the south-eastern side runs along the Varda river to Mount Mavrovouni (2,100m) near Metsovo. The municipality has an area of 989.796 km and its population is about 3,700.
Zagori is an area of great natural beauty, with striking geology and two National Parks, one including the river Aoos and the Vikos Gorge, the other around Valia Kalda, to the east of the imposing snow-capped Mt Tymphe. The 46 or so villages of Zagori were interconnected by mountain roads and traditional arched stone bridges until modern roads were opened in the 1950s. The stone arched bridges were built by benefactions from expatriate merchants in the 18th century and replaced older wooden bridges. Furthermore, the region has been historically difficult to access due to its mountainous terrain which likely contributed to its unique character. The Sarakatsani people who can be found in this area use several Greek words of a Northern Greek dialect not commonly found in Greek elsewhere. They are consequently considered by some as indigenous to the area.
