The route starts from Bovec, near which are the Ravelnik and Čelo Open-Air Museums, and heads towards the confluence between the Koritnica and Soča rivers near Vodenca. Then it proceeds along the right bank of the Soča up to the Kršovec Gorge where, after crossing the river, the separation with stage 2 occurs. Stage 2 continues towards Mount Golobar, while B-KG 1 turns left after the bridge, following the river to the magnificent area of the Great Soča River Gorge. From here, the route continues along the Soča Trail to the homonymous settlement, interesting both for the Austro-Hungarian cemetery behind the Church of St. Joseph and for the church itself, frescoed by Slovenian painter Tone Kralj. From Soča, the path climbs along a valley towards Trenta, arriving at Dom Trenta, home to the Julian Alps Ecoregion infopoint and the Triglav National Park Museum.
