Located along the northern slopes of the Vratza Mountain, the Vrachanski Karst Reserve is one of the most dramatic and picturesque natural sanctuaries in Bulgaria. Integrated within the Vrachanski Balkan Nature Park, the reserve protects towering limestone cliffs, rugged gorges, and fascinating karst formations spanning altitudes between 250 and 850 meters.
Established on August 10, 1983, and covering over 1,438 hectares, Vrachanski Karst was created to preserve its iconic karst landscape, unique cave fauna, sub-Mediterranean flora, and numerous relict plant species protected by the Bulgarian Biodiversity Act and featured in the Red Data Book of Bulgaria.
The reserve stretches from the village of Pavolche to the Zmeyova Dupka cave, divided almost symmetrically by the Leva River into two main sections: the Bazovski and Stresherski ridges.
The territory of the reserve and its immediate surroundings harbor some of the most famous natural and historical sites in the region:

Suitability depends on the specific route. Bulgarian trails range from paved family-friendly paths to multi-day high-mountain crossings. Check the length, elevation gain, and surface before setting off. Sturdy footwear, water, and a basic map (offline or paper) are essential even on short walks.
