and its bridges

The Isonzo-Soča River stretches some 136 kilometres from its source in Slovenia’s Trenta Valley — winding through nearly 100 kilometres of Slovenian territory before continuing its journey across 40 kilometres of Italian territory — until it flows into the Gulf of Trieste.

Along its course, the river passes through Bovec, Kobarid, Tolmin, Solkan, Nova Gorica, Gorizia, Gradisca, Sagrado, Fogliano, San Pier d’Isonzo, Fiumicello, San Canzian d’Isonzo and Staranzano.

Beyond its upper course-where it flows torrentially through the extraordinary landscape of the Trenta Valley with its bends, ravines, gorges, and waterfalls — the riverbed widens past Bovec into its middle course. In its lower stretch, the river reveals its full majesty, displaying its distinctive emerald-green waters.

After entering Italian territory at Gorizia, the river’s influence becomes so profound that it gives its name to the surrounding area: the Isontino. Finally, the river shapes the natural landscape, winding through lush vegetation and creating graceful meandering bends before flowing into the sea.
