Mrtvica Canyon is 35km from Kolasin, in the direction of Podgorica, and it is around 9km long. The banks of the river Mrtvica, the right tributary of the Moraca river, are steep, high and abundant with vegetation. At certain places, they are more then 1100m high. The narrow sandy path has carved its way through the canyon. Especially attractive are springs called "Bijeli nerini" – "White nerins". On the Mrtvica river near Zeleni vir (the Green whirlpool), there is an old stone bridge built by prince Danilo as a memorial to his mother. The river’s clean waters abound with trout, huchen and other rare species.
