The trail starts from Trail 10 after a five-minute ascent from the intersection with Trail 11 (944 m altitude). Walk on the animal path through the deciduous forest that gradually becomes more rare and gives way to a 7-8 meter wide passage. After about 160 meters altitude difference, the increasing slope gets to a scree area, where you have to follow the easiest switchbacks up. Continue the steep ascent to 1310 meters, where there is a 4-5 meter deep cave on the right wall (left geographical wall) with water dripping on the wall at the end of the cave. While climbing, pass three rocky steps along the stream (one of them has a cable which is partly fixed into the rock), continue right and when you get to 1480 m cross to the left side of the valley on a rocky ledge above the last rocky step. After an 80-meter ascent (30% slope), enter the rocky path among dwarf pines and walk for about 130 meters (20% slope). Get out of the dwarf pine area, climb along the left geographical wall beside the scree, get above it on the right geographical side of the valley to a grassy crest (resting place). From here, continue up on the edge covered with dwarf pines for 200 meters and the path continues past a vertical wall to the left. Cross a rocky step between the wall and the dwarf pines and after a 10-minute ascent reach Trail 20 at an altitude of 1863 m, 50 meters below Varful Turnu peak (1923 m).
