The Gacka Valley is a great karst field, surrounded by Velebit in the sea direction and by Kapela in the mainland direction. The water of the Gacka River is exceptionally clean and rich in oxygen, so there are many protected plant species growing in the river.
There old mills “malenice” placed on the Gacka’s springs, some of which were renewed on the traditional style. The residents who lived in the Gacka Valley (gačani) used “plavi” to get around the river, vessels, carved from fir logs. The oldest evidence of human activity in the valley stems from the Mesolithic Age, and this area was of great importance in the later Croatian history, as well. The flora and fauna of the river are both very numerous. The water undergrowth is lush due to the favorable water temperature, beneficial chemical properties, silty bed, from moss and algae to stalk-shaped plants
