The source of the river Soča is located in the Alpine valley of Trenta, not far from the main road leading to the Vršič Pass. Water from the peaks of the Julian Alps comes bubbling out into the open from a cave with an underground lake. The initially narrow gorge soon widens and follows the lively Soča on its 138 km journey to its mouth in Italy (where it is known as the Isonzo). The river’s source is a wonderful natural sight, although a little bit out of the way, so reaching it requires a certain amount of skill. Follow the marked path for around 15 minutes to reach the source. The first part of the path is easy but it becomes steeper towards the end, with a steel cable to help you past the most difficult sections. Hiking boots are recommended.
Not far from the spring you can see the monument to the mountaineer Julius Kugy, follow the path over the gravel beds of Zapoden and seek inspiration in the Alpine botanical garden Alpinum Juliana. The magical valley of Trenta will entrance you with its beauty, tranquillity and unspoilt nature, proudly conserved by the local inhabitants.
