The entire development area of the gorge is a set of geological features, each representative of specific geological processes. A panoramic view of the stratigraphic sequence of the Ionian Zone limestones, river erosion structures, karst conduit exposures, and significant spring manifestations, river terraces, rock shelters, faults, and folds are some of the interesting elements that define the geological setting of the area. In the Upper Pleistocene, the retreat of glaciers released large quantities of water, which rapidly eroded the limestone formations and created the impressive gorge. The strata are sub-horizontal, and the stratigraphic sequence of the Ionian Zone from the Upper Jurassic to the Lower Miocene is revealed on a natural scale. At the base of the Gorge are the dolomitic limestones of Vigla, aged 160 million years, and at the top are Eocene limestones, aged 40 million years.
The magnificent landscape is world-renowned and a destination for thousands of visitors. Contact with the area is made either by crossing the gorge on a hiking trail or from panoramic viewpoints, which have been suitably designed.
