Cerknica Regional Park is a unique karst wetland reserve famed for the intermittent Cerknica Lake, offering diverse ecological habitats and rich outdoor recreational opportunities in Slovenia’s Dinaric Alps region.
Cerknica Regional Park encompasses a remarkable karst landscape centered around the intermittent Lake Cerknica, one of Europe's largest temporary lakes. Located in southwestern Slovenia, the park spans a mosaic of wetlands, forests, meadows, and caves characteristic of the Dinaric Alps' limestone formations. The lake fills and drains seasonally, transforming the landscape dramatically throughout the year and creating vital habitats for a wide array of flora and fauna. This dynamic ecosystem supports rare and endangered species, including migratory birds, amphibians, and several endemic plants. Visitors to Cerknica Regional Park enjoy birdwatching, hiking, cave exploration, and seasonal fishing opportunities. Historically, the region has been settled since prehistoric times, with cultural heritage reflected in local villages and traditional land uses like haymaking in the wet meadows. The park's karst phenomena—including sinkholes, underground rivers, and caves such as the Big Mount Snežnik Cave—offer fascinating natural landmarks. The Visitor Centre provides educational exhibits highlighting the park's geological and ecological importance, enhancing visitor appreciation. Outdoor enthusiasts can explore marked trails that offer panoramic views, and in certain seasons witness the remarkable cyclical flooding and drying of the lake. The park appeals especially to those interested in geology, birdlife, and experiencing a rare natural hydrological phenomenon alongside rustic Slovenian rural culture.
