Slovenia offers an outstanding mosaic of biological, landscape and cultural diversity. So far 11.5% of the Slovenian countryside has been protected in various protection categories. Altogether there are forty-four protected areas or parks, including one national park, three regional parks and forty landscape parks.

The largest protected area in the country is the Triglav National Park, which encompasses nearly 4% of the territory of Slovenia (83,807 ha). The park’s diverse configuration consists of mountain ridges, glacial valleys and lakes, surface and subterranean karst phenomena typical of high-lying areas, the sources of the Sava and the Soča rivers with numerous waterfalls and deep river beds. The vegetation in the park is mainly Alpine with numerous endemic species. Among the characteristic animal species of the area is the endemic Soča trout.
