Pirin

The Pirin Mountains are a range in south-western Bulgaria, about 80 km long, with their highest peak, Vihren, at 2,914 m. Pirin is dotted with more than a hundred glacial lakes, and most of the range is Pirin National Park, a UNESCO World Heritage Site.

The lakes here include Popovo Lake, the largest and deepest in Pirin, the Banderitsa lakes, Tevno Lake, Muratovo Lake below Vihren, and the Vlahini lakes.
