River Cetina is 104 km,lng and the water from the river Cetina is forwarded to few power plants in the Split hinterland. The amount of water that flows through the fascinating natural canyon is enough for a summer rafting, but during the rainy season it can be converted to rapid and turbulent river. River runs through the mountain range Mosor making impressive, deep and beautiful canyon. After a relatively long course creates some very impressive passages like Gornjačka, Dragovićka, Derventska, Obrovačka (near Obrovac Sinjski) Trilj (in Trilj) and Zadvarska (in Zadvarje). Rafting on Cetina rolled in rafts for 6 to 8 people, each raft has a professional escort. Duration of driving is about 4 hours and each guest gets a vest, helmet and paddle. The aim is to Radman mill.
