The Isonzo is the alpine river springing in the Julian Alps on the northern slopes of Trenta valley. The name of the river Soča (in Slovenian) or Isonzo (in Italian) became in history of Great War a synonymum for mass battles associated with the unprecedented use of forces and resources, but also with huge human losses. That is why Isonzo is called the "bloody river".
Isonzo flows through the Trenta valley to the south, then to the southeast and flows around Bovec. At Žaga, Isonzo turns to the southeast toward Kobarid (in Italian Caporetto) and then runs past towns Tolmin, Kanal ob Soči, Deskle and Plave. In this section are mountain ridges on both sides of watercourse towards Gorizia where the hard fighting of the Great War took place. Isonzo leaves Slovenian territory at Solkan and heads to the southwest towards Gradisca d'Isonzo. Isonzo enters the Adriatic Sea close to the town Monfalcone.
