Lake Cerknica is one of the largest karst lakes in Europe and is located in the southwestern part of Slovenia near Cerknica. The lake is part of Cerkniško polje, an area known for its extraordinary karst phenomena.

The special feature of Lake Cerkniško is its variable nature. The lake changes throughout the seasons, depending on rainfall and karst waters. During periods of heavy rainfall, the lake fills and reaches an area of up to about 30 square kilometers, making it the largest permanent intermittent lake in Europe. During this period, the lake attracts many birds and other animal species.

When the lake is emptied, shallows, bogs and marshes are exposed, which are home to many plant and animal species. It is an important wetland and an area inhabited by rare species of birds such as black stork, marsh tit, great hornbill and many others. Cerkniško Lake is also an important international ornithological area.

There is a network of walking paths along the lake that allow visitors to explore this unique natural environment. There are observatories where visitors can see birds and other animal species in their natural environment. The lake is also popular with fishermen as it is home to many fish species such as carp, pike, catfish and many others.

Lake Cerkniško is also an important part of local culture and tradition. Around the lake there are many historical and cultural attractions, such as Snežnik Castle, churches and traditional farmhouses. The area is popular for excursions, picnics and other outdoor activities.

Notranjski regional park is also located near the lake, which protects and preserves the natural and cultural heritage of this area. The park offers additional opportunities for exploring the karst landscape, caves and other natural attractions.

Lake Cerkniško is an attractive destination for nature lovers, ornithologists, photographers and anyone who wants to experience a unique and changing natural environment.
