From close to the monument to Dr Julius Kugy on the road over the Vršič Pass, a side road takes you about 1.3km to a simple mountain lodge (named Koča pri Izviru Soče, with beds and food), and from here you can take a 15-minute walk along the first part of the Soča Trail to the source of the Soča River.

Fed by an underground lake, the infant river bursts from a dark cave before dropping 15m to the rocky bed from where it begins its long journey to the Adriatic.
