The Soča river spring is as special as she is herself. The Emerald beauty is born in the high karst spring in Trenta valley, where collected water from surrounding peaks bursts out to the surface. You can walk to the spring from the hut called Koča pri izviru Soče. It surely is an amazing experience. However, paying attention on the way and good shoes will not be redundant, because the path is in some places quite steep.
