At War

Soca River

{Formerly Isonzo}

Rising in a natural spring in the high Julian Alps at 1050 meters near village of Soca, the 136-km long Isonzo [Soca] flows from the Triglav National Park in northwestern Slovenia to the Adriatic. The aquamarine Isonzo [Soca] is one of the most beautiful and cleanest rivers in Europe. Its upper stretch [a non-Great War Area] has magnificent gorges in the Trenta valley and the Boka Waterfall, highest in Slovenia. It is a world class attraction for those wishing to engage in active forms of recreation, especially fishing, camping and various types of boating. The steeper upper sections of the untamed alpine river attract canoeists from all over the world and rafting is also becoming increasingly popular.
