Psaho Canyon is actually two canyons: Mokryi (Wet) and Sukhoi (Dry).
Mokryi is 1.5 to 10 meters wide; for 2 kilometers there are karst channels and baths, small waterfalls and watercourses, fantastic grottoes and giant layered calcareous layers that make the Psakho banks.
Sukhoi is larger in size. It's located higher from the river bed, in 20-30 minutes of walking distance. Giant fracture in limestone strata, formed as a result of an earthquake.
