The significant landscape of the Cetina canyon since 1963 stretches from Tisno to the mouth. In 1774, an Italian biologist, travel writer Alberto Fortis, wrote about canyon of Cetina in his work “The Way to Dalmatia”. The protected canyon is diverse. In some parts of the canyon, the canyons are fairly widespread and relatively laid, so there are subwalls of once-treated surfaces, but which are most commonly poorly seen today because they are covered with macchia and forest due to the neglect of traditional agriculture. On some sections the canyon is extremely narrow and steep and has vertical cliffs. A special attraction is the waterfall of Velika and Mala Gubavica. The canyon alone, in other words is a geomorphologic phenomenon characterized by karst, where the river with the work of water carves into the limestone base. Over 100 kilometers long, Cetina offers an abundance of adventure tourism and extreme sports thanks to the natural conditions of the Cetina canyon. As a reminder of the turbulent history of these regions, almost all of the Cetina River stretches along numerous medieval forts. Some of them are well hidden and partially destroyed, while others today are proud of their elevations and serve as lookouts. It is an ideal place for an active holiday and a stay in nature.
