The trail starts and ends at the Koča pri Peričniku, but if you want to extend the trail, you can start in Mojstrana (Slovenian Alpine Museum) and follow the Triglavska Bistrica Trail, which also leads to the Koča pri Peričniku.
Peričnik is the name of the waterfall and the stream that flows into the Triglavska Bistrica stream near the Koča pri Peričniku. The formation of the waterfall is linked to the glacial transformation of the Vrata valley. The valley through which the Peričnik flows is a so-called hanging valley above the deeper, larger Vrata valley. Water erosion has created two waterfalls - the Upper and Lower Peričnik. The upper part of the Lower Peričnik consists of conglomerate, while the lower part is dominated by crumbly breccia, which has also formed potholes, allowing a path to be made around the waterfall.
