The Gorenja Trebuša – Dolenja Trebuša road is situated in the western part of Slovenia, within the Primorska region. The route connects the settlements of Gorenja Trebuša and Dolenja Trebuša, following the Idrijca river for a significant portion of its length. The surrounding landscape is characterized by forested hills and river valleys, offering a tranquil environment away from major urban centers. The road’s proximity to the Idrijca river, which ultimately flows into the Isonzo, adds to its appeal for those interested in natural features.
