Its 105km-long journey to the sea the River Cetina starts at the foot of the Dinara mountain, supplying several sources with water at an altitude of 380 m, of which the most abundant are the Glavaš spring, Vukovića spring and Batića spring.

The springs merge in Lake Peruča, from where the River Cetina continues its course in the direction of Omiš, where it flows out into the Adriatic Sea.
