Aggtelek

Aggtelek National Park, established in 1985 in northeastern Hungary's Borsod-Abaúj-Zemplén County, is renowned for its extraordinary karst landscape and the Aggtelek Karst cave system, which it shares with Slovakia as a UNESCO World Heritage Site. Spanning approximately 198 square kilometres, the park encompasses the largest stalactite cave network in Europe, with Baradla Cave extending 25 kilometres across the Hungarian-Slovak border. The park's surface is characterised by sinkholes, dry valleys, and limestone outcrops that create a mosaic of habitats supporting remarkable biodiversity.
