Vrachanski Balkan Nature Park, Nature park in Vratsa, Bulgaria.

Vrachanski Balkan Nature Park covers 30,129.9 hectares of the Vratsa mountain in Bulgaria's western Stara Planina, including the Lakatnik and Cherepish rocks in the Iskar Gorge. Its carbonate Triassic and Jurassic limestones hold about 500 caves and chasms, among them Ledenika, the New Cave, and Temnata Dupka. The park lies in the municipalities of Vratsa, Krivodol, Mezdra, Varshets, and Svoge.

Vrachanski Balkan Nature Park was established on 21 December 1989 by Order No. 1449 of the Committee for Environmental Protection, covering 30,129.9 hectares. In March 1997 it became a protected area of international importance, and the IUCN lists it in category V as a protected landscape. The park is administered by a directorate under the Executive Forest Agency of Bulgaria's Ministry of Environment and Water.

The Cherepish Monastery sits on the bank of the Iskar River and is still home to monks who keep Orthodox traditions alive in the region. In the villages nearby, local people maintain old customs tied to the land and the changing seasons.

The park is best visited in the warmer months when trails are more accessible and conditions are more stable. Anyone planning to explore the gorge or caves should wear sturdy footwear and be ready for weather that can change quickly in the mountains.

Among the many caves in the park, Ledenika Cave is known for the natural ice formations that build up inside it during winter. Even in summer, the cave stays cold enough that the air inside feels noticeably different from the warmth outside.
