Omiš Day Trip from Split: Boat Cruise, Fortress Walks & Swimming at Radman’s Mills

You step off the bus in Split and an hour later the air has changed—salt and pine, the Cetina river murmuring like a promise as the Adriatic widens beneath low cliffs. The town of Omiš sits where the river meets the sea, squeezed between two limestone ridges; its stone houses climb toward Mirabela Fortress, which keeps watch like a committed lookout. A local guide—Professor Mario, who teaches history and geography—leads the group through narrow alleys, pointing out the parish church of St. Michael and the scars of a past when Omiš’s pirates stalked these waters.
