Cetina River Near Omis, Croatia. Editorial Photo

Cetina is a river in southern Croatia. Cetina has its source in the northwestern slopes of Dinara. Rising from a spring at Milasevo near a small village called Cetina it flows 101 kilometres to the Adriatic Sea, in the city of Omis. Bounded to the east by the Dinaric Alps, which rise to an elevation of 2,000 metres, and to the northwest by mountain Svilaja, the majority of the catchment drains calcareous rocks of Cretaceous age, predominantly limestone. Rocks of Triassic and Jurassic age also crop out in the catchment and include dolomitic limestone and flysch. The underlying karst geology controls relief with a series of structurally aligned basins separated by high ridges. The canyon of the river Cetina is very popular among tourists looking for adventure activities like rafting, canyoning, zip-line, rock climbing, kayaking and other outdoor activities. Croatia, Europe.
