To the left of Lajšt one can easily follow the water flow of the river Belca. The water is clean and the nature is well-preserved. In this section of the park there are no permanent residents and during the last two years of World War II in almost impassable areas one could come across the Partisan Hospital Pavla providing care for around1,600 wounded men. The road takes us past two klavže, wood post at Krekovše and after about 15 km we arrive at the pass dividing the valleys of Idrijca and Trebuša.
