The particular character of the Borbera valley consists in its nature, which in a large part is still uncontaminated and wild. The strongly modelled range, covered in a rich cloak of vegetation, is populated with numerous wild animals finding here their natural habitat. In sharp contrast to the mountains is the gigantic gorge on the valley floor called “Strette”, with plenty of bights and meanders, excavated by the torrent Borbera. It represents one of the most suggestive areas of the territory.
