How to reach Vratsha ?

Some important road information:

Vratsa region
Within this region, most of the mountain Vrachnska Planina is situated – a band oriented NE-SW. It rises sharply above the plain of Vratsa and the hilly area of Mezdra – bordering it on the northeast. The slopes are abrupt, rocky, about 600 - 700 m high. The valley of Leva River subdivides it into two parts: Bazovska (southeastern) and Stresherska (northwestern), with the highest summits respectively Buk (1394 m) and Streshero (1212 m). The valley of Leva River has formed the picturesque gorge Vratsata between Zgorigrad and Vratsa.
In general, plateau-like relief is typical here with peneplenized surface, mainly between 1000 and 1200 m a.s.l. The peneplenized area features a typical karst relief with residual tumuli, separated by poljes, blind dolines and blind valleys. Other surface forms are developed as well - funnels, karren, karren fields.
Vrachanski Balkan Nature Park has a territory of 28,844 hectares, most of which is covered with karst limestones, 1,300 meters thick. Unique in their beauty caves and chasms can be seen in the park. Their total number is above 500. On the territory of the park about 950 species of high plants have been registered, of which more than 80 are rare species. From a scientific and preservation point of view the most interesting species are the groups living in the caves (vertebrates and bats) and the day birds of prey. There are 214 registered species of vertebrates in the park.
Within the limits of the park lies the reserve Vrachanski karst. It covers an area of 1453.1 hectares, situated along the northern stone cliff slopes of Vrachanska Mountain. The territory of the reserve is inhabited by the rare and endangered species of Egyptian vulture, peregrine falcon, short-toed eagle, long-legged buzzard, 8 species of bats etc. The Natural park “Vratchanski Balkan” occupies the biggest area of the Vrachanska mountain and the massive of the Lakatnishkite skali.
For the forming of karstic features here, especially important is the thick Upper Jurassic and Lower Cretaceous limestone. Underneath, there are rocks of Middle and Lower Jurassic (aleurolyths and aleuryths), missing in some places. A Trias carbonate complex (karstified limestone and dolomite) follows. In their base, they transit into Lower Trias sandstone and aleurolyths.
As a whole, in the area there are more than 250 caves and potholes were known More numerous,
although smaller are the caves in the eastern part. However, in the western part most of the bigger cave potholes are situated. So far, in Vratsa There are seven cave potholes and proper potholes over 100 m deep (some of them also of considerable length).
