To join to the events of the International Geodiversity Day (October 6) on our Geoptop Saturdays (October 7 and 14) special programs celebrate the rich geodiversity of the transnational Novohrad-Nograd UNESCO Global Geopark. At its main gateway, the Ipolytarnoc Fossils Nature Reserve, managed by the Bükk National Park Directorate and at the Karancs subvolcano geosite guided tours are organised.
