The Zelenci nature reserve is located at the three-country border, (Slovenia, Italy & Austria) its primary significance being as a testimony to the area’s geological past. Many rare and unique animal species, as well as some sparse and endangered plants have found their haven at Zelenci.
The unspoiled and pristine natural surroundings of Zelenci along with its close vicinity to the emerald green lake, and with the area’s countless springs provided inspiration for the beautiful canvas paintings by Ladislau Benesch and was praised by the great naturalist Davy.
The famous naturalist Sir Humphry Davy expressed his appreciation of the beauties of this mountainous area in the following words: "Most of all I am fond of the Savska valley with its waterfalls and lakes. There is no other more beautiful spot in Europe".
