  The numerous fossil finds, the powerful so-called Idrija Fault, tectonic window Strug... demonstrate and prove at least a part of the complex geological structure of this region.

The olds stones date back to the Carbon period and below the Sončni rob the moraine dams from Pleistocene Ice Aeriod stand out.

Almost the entire area of the park, except on the edges of Trnovski gozd, boasts vast surfaces of water. The Idrijca river with its numerous confluents is the main artery. It rises at an altitude of 840 m above sea level, after a 450 m decline it is joined by the Belca River, and at the altitude of approximately 350 m it can no longer be seen within the park’s area. It is accompanied by many confluents, some of which have a steady, powerful spring and others with fast-flowing streams. About 2 km to the rear, it forms its confluence and the Idrijca and Belca current changes its course from SE to NE for 90°. The reason for this phenomenon probably lies in the powerful and faster-moving erosion of the Soča basin. Thus, Soča inverted the course of waters within the park’s area from the direction of Godovič and Hotedršica towards Posočje.
