Slovenia to Celebrate UNESCO International Day of Caves and Karst for the First Time
Slovenia will celebrate UNESCO’s International Day of Caves and Karst for the first time on 13 September 2026. Established following a Slovenian initiative, the international day highlights the country’s special role in karst science, speleology and the research and protection of underground heritage. The inaugural celebration will include an international scientific conference, a central ceremony in Postojna Cave and a series of accompanying events.
Events will take place under the honorary patronage of the President of the Republic of Slovenia, Dr Nataša Pirc Musar, and the patronage of UNESCO, with the support and participation of the Slovenian National Commission for UNESCO, Postojna Cave, Škocjan Caves Park, the municipalities of Postojna and Pivka and the Speleological Association of Slovenia.
Slovenia at the heart of international karst science
An important part of the inaugural celebration will be the international scientific conference Explore, Understand and Protect: Towards Sustainable Management of Caves and Karst, taking place in Postojna from 10 to 13 September. The conference will focus on cave and karst research, conservation and sustainable management.
The central ceremony will take place in Postojna Cave on Saturday, 12 September, bringing together scientists, speleologists, decision-makers, UNESCO representatives, members of the diplomatic corps and other Slovenian and international guests. The establishment of the international day following a Slovenian initiative is an important recognition of Slovenia’s long-standing contribution to karst science and speleology. It also draws attention to the importance of protecting caves and karst landscapes for future generations.
The very word karst comes from Slovenia’s Kras region. This angle explores how the country helped shape the scientific understanding of karst landscapes and why Slovenia remains an important centre for cave and karst research today.
Postojna Cave may be the best-known name, but Slovenia’s subterranean landscape is far more diverse. From the UNESCO-listed Škocjan Caves and the underground lakes of Križna jama to Planina Cave and Vilenica, there is plenty to discover beyond the classic highlights.
A useful travel feature comparing Slovenia’s two most famous cave experiences: Postojna Cave, known for its vast chambers, underground railway and olm, and the Škocjan Caves, famous for their monumental underground canyon and UNESCO World Heritage status.
The underground story is only part of the experience. Above ground, travellers can combine caves with stone-built villages, Teran wine, local prosciutto, cycling routes and the distinctive cultural landscape of the Kras region.
A first-person adventure story taking journalists beyond Postojna Cave’s classic visitor route and into its less accessible passages, combining exploration, history, biodiversity and the extraordinary underground ecosystem that is home to more than 150 animal species.
