Balkan Mountains - Geography

Geography

Geologically, the Balkan Mountains is a 'young' part of the Alp-Himalayan chain which stretches across most of Europe and Asia. It can be divided into two parts: the main Balkan Chain and the Pre-Balkans to the north, which intrude slightly into the Danubian Plain. To the south, the mountain borders with the Sub-Balkan valleys - a row of 11 valleys running from the border with Serbia to the west to the Black Sea to the east which separate the Balkan mountains from a chain of other mountains known as Srednogorie which include Vitosha and Sredna Gora.

The range consists of around 30 portions called mountains. Stara Planina can be divided into three sections:

• Western Stara Planina from Vrshka Chuka at the border with Serbia to the Pass of Arabakonak with a total length of 190 km and highest peak Midžor (2,169 m).
• Central Stara Planina from Arabakonak to the Vratnik Pass with a length of 207 km. Botev Peak (2,376 m) which is the highest in the range is located in that section.
• Eastern Stara Planina from the Vratnik Pass to Cape Emine with a length of 160 km and highest peak Balgarka (1181 m). Eastern Stara Planina forms the lowest part of the range.

Stara Planina forms a water divide between the rivers flowing to the Danube in the north and those flowing to the Aegean Sea in the south. However, it is crossed by Bulgaria's widest river, the Iskar, which forms the spectacular Iskar Gorge. Rivers which take their source from Stara Planina and flow northwards to the Danube include Timok, Archar, Lom, Tsibritsa, Ogosta, Skat, Vit, Osam, Yantra, Rusenski Lom. It is also the source of the Kamchia which directly flows in the Black Sea. Although not so abundant in mineral waters as other parts of Bulgaria, there are several spas such as Varshets, Shipkovo and Voneshta Voda. There are a number of waterfalls, especially in the western and central parts of the range such as Raysko Praskalo which is the highest waterfall in the Balkan Peninsula, Borov Kamak, Babsko Praskalo, Etropole Waterfall, Karlovsko Praskalo, Skaklya and others.
