Extending over a great area and lying at an altitude of 1,008–2,914 meters in the Pirin mountain, in south-west Bulgaria, Pirin National Park has a limestone South Eastern Europe landscape, with lakes, waterfalls, caves and pine forests. The rugged mountains, with some 70 glacial lakes scattered throughout them, are home to hundreds of endemic and rare species, many of which are representative of the Pleistocene flora of the region. The mountains also have diverse and unique landscapes of great aesthetic value.
