At Mount Lussari, the Julian Alps, the Carnic Alps, and the Karawanks meet. Its waters flow toward both the Adriatic and the Black Sea. The valleys of the Drava, Sava, Soča, and Fella all lead to this mountain.

From a geographical perspective, Mount Lussari is truly unique. It is like an island from which four important river systems originate or are nourished. Part of its waters flow north into the nearby Drava River, while those on its southern slopes feed the Fella River, which eventually reaches the Adriatic Sea. To the east, two low mountain passes separate the Canal Valley from the headwaters of the Sava and the Soča (through the Koritnica stream), whose waters flow into two different seas. The Canal Valley—and especially Mount Lussari—is the meeting point of four important Alpine valleys. Reflecting on this mountain, Professor Lambert Ehrlich, a native of the Canal Valley, wrote that the border on Mount Lussari does not divide but unites three great cultural traditions: the Slavic, the Germanic, and the Romance.

Today, Mount Lussari lies within the protected Tarvisio Forest, one of the best-preserved wildlife habitats in the Alps, designated as a natural biogenetic reserve. To the south, it is embraced by the imposing cliffs of Montasio and Jôf Fuart, which completely close the view toward Friuli. To the north, the landscape opens toward the Drava Valley, Carinthia, and the interior of Austria. To the east rise the Ponze Mountains, Mangart, and Jalovec. To the northeast, the Karawanks separate the valleys of the Sava and the Drava, while Mount Cima del Cacciatore to the southeast provides a magnificent backdrop to the summit of Mount Lussari. To the west, the view extends toward the Carnic Alps and the Großglockner massif.

The area is crossed by a network of forest roads and mountain trails. Shepherds and pilgrims—the mountain’s earliest visitors—are now joined by countless hikers, cyclists, and paragliders. The entire area forms part of the ancient and protected Tarvisio Forest, renowned for its rich flora and fauna.
