River Gacka that springs in The Gacka Valley near Otočac is the third-longest sinking river in the world and her beauty is truly one of a kind.
The waters of Gacka are extremely clean and rich in oxygen and the Gacka source area consists of numerous and picturesque springs, the three strongest among them: the Tonković Vrilo, Klanac, and Majerovo Vrilo.
Let`s go see them from the bird`s eye view!
