An easy/semi-demanding biking trail that leads along the Soča River and the Lepenica Stream to the Lepena Valley.

The tour starts at the turn-off for Lepena on the Bovec - Trenta road.
Following the asphalt road via the right bank of the Soča River, one reaches the Klin campsite.
At this point the road turns and continues towards the Lepena Valley.
A bit before the end of the valley, the road leaves the Lepenica Stream and ascends steeply up to the lodge of Dr. Klement Jug.

The starting point of this tour may be combined with sightseeing at the Great Gorge of the Soča River, while the end of the tour offers yet another (mountaineering) experience: climbing up to the Krn Lakes.
