Vitosha Nature Park, the oldest park in Bulgaria and in the Balkan Peninsula. It was instituted in 1934 and after several extensions acquired 26,606.6 ha. The park is a mountain massif with steep slopes and extensive plane grounds. Chemi Vruh (2290 m) is the highest peak; 27 peaks rise 1500 m and more. The moraines or well-polished syenite debris carried down and deposited by glaciers are typical of Vitosha. The ridge is one of the wettest places in the country. The park is the habitat of 1500 higher plant species and of almost one third (120) of the bird species in Bulgaria. There are two reserves: Bistrishko Branishte (declared in 1934) and Torfeno Branishte (declared in 1935). The former is included in the Man and Biosphere Program and listed as an area of international importance. During the weekends over 100,000 people daily visit the park.
