North Macedonia is a predominantly mountainous country. The average elevation of the terrain is 850 meters. Approximately 80% of the country consists of hills and mountains. The mountains are divided into two basic groups: on the one hand in the North-West the Šar Mountains mountain range that continues to the West Vardar/Pelagonia mountain range in the South-West and South (contiguous with the Dinaric ranges). On the other hand, in the South-East the Osogovo-Belasica mountain chain (westernmost section of the Rila-Rhodope Mountains).
