The Gacka River is one of the most sought after destinations and most renowned trout waters in Europe and the world. It takes you an hour and a half to get there by car from Zagreb. Gacka is a gulf river which, for 11 kilometres, gently winds down the Gacka valley plain from its spring in the southeast, to the gulf in the northwest. The Gacka is a typical chalk-stream. It is exceptionally rich in flora and fauna. The vegetation is abundant because of the favorable water temperature, convenient chemical composition, silty river bed, and moderate flow. Underwater vegetation grows throughout the year, but more intensively in the warm seasons. Twenty-five plant species have been identified, from algae and bryophytes to woody plants.
As far as the fish species are concerned, the Gacka is famous worldwide for its brown trout. As well as brown and rainbow trout, there is also grayling in the Gacka, and some other fish species. Brown trout in the Gacka grow five times faster than in other limestone rivers, because of the stable water temperatures, plenty of oxygen and the water's mildly alkaline chemical composition. The secret of the Gacka lies in all the fauna that abounds in it. We know of 17 aquatic animal communities, i.e. organisms spread throughout the river's entire course, constituting the basic nourishment for the brown trout, and to which it owes its unusually rapid growth.
