To the north Pirin is separated from Bulgaria's highest mountain
range, the Rila Mountains, by the Predel saddle, while to the south it
reaches the Slavyanka mountain. To the west is located the valley of the
Struma and to the east of the Mesta Rivers. Pirin is noted for its rich
flora and fauna. Much of the area is forested, with the best conifer
woods in Bulgaria, holding important populations of the Balkan endemic
species Macedonian Pine, Bosnian Pine and Bulgarian Fir. Animals include
the wolf and the Brown Bear.
The town of Bansko, an important
tourism and winter sports centre, is situated on the northeast slopes of
the Pirin Mountains. The town of Razlog lies in Razlog Valley between
Pirin Mountains to the south and the Rila Mountains to the north
