The canyons are part of a not leaving nature (geo-monuments) and are grouped in relation to their origins and the geomorphologic and geological characters. They are created based on the erosion and dilution power of water, penetrating slowly and without stopping in the rock dividing it in two parts. When you travel inside or observe them, you are fascinated from their amazing beauty, but also from several wandering impressions that are produced: part of the sky together with the vertical walls of the rocks, green plants that are reflected in the water pools creating a mixture of colours and reverse forms.
In Bioland there are 25 canyons part of the national list of the Nature Monuments designated to be protected for their nature value presenting.
