Travelling along the Soča River in Italy and Slovenia
I am now making my way along the Soča, an emerald green river in Italy and Slovenia best known for being the location of twelve battles during WW1 between Italy and Austria Hungary. Along its 128km course, the traveller is treated to wonderful mountain scenery as well as the unique colour of the river itself. This is one of the few rivers in the world that manages to keep such a colour along its entire course.
The source of the Soča lies in the Trenta Valley in the Julian Alps in northwestern Slovenia, at an elevation of 876 metres. On its way south to the Adriatic Sea it passes Bovec, Kobarid, Tolmin, Kanal ob Soči, Nova Gorica (where it is crossed by the Solkan Bridge), Gorizia and Gradisca d'Isonzo entering the Adriatic Sea close to the town of Monfalcone.
The Soča is known for its unique trout species Salmo marmoratus (the marble trout), which lives in the upper course of the crystal-clear river. This species is endangered due to competition from introduced non-indigenous trout species in the interwar period.
