About Osogovska Planina#

Osogovska Planina is a mountain range on the border between southwestern Bulgaria and northeastern North Macedonia notable for rounded peaks and mixed forest cover. The range features alpine meadows, summer pastures and a number of hiking trails used by local and regional visitors.
