Macedonia is a predominantly mountainous country. The average altitude of the terrain is 850 meters. Approximately 80% of the country consists of hills and mountains. The mountains are divided into two basic groups: Šar Mountains mountain range that continues to West Vardar/Pelagonia mountain range (also known as Dinaric range) and Osogovo-Belasica mountain chain (also known as Rhodope range). Šar Mountains and West Vardar/Pelagonia mountain range is a continuation between the Dinaric Alps and Pindus mountain ranges, whereas Osogovo-Belasica mountain chain is a continuation of the Rila-Rhodopes mountain massif.
"Macedonia's terrain is mostly rugged, located between the Sar and Osogovo mountains, which frame the valley of the Vardar river. Macedonia's high mountains are suitable for winter sports and hunting. About 35% of the former Yugoslavia's ski slopes could be found in Macedonia.".
