Time Out says
Sail down the Kupa river
Down the Kupa from Karlovac, Brođani typifies the riverside villages that relied on small boats for their livelihoods. Now visitors can go on a 90-minute sailing trip in a replica of one of these vessels, the Zora. Every weekend morning at 11am, instead of grain, this sturdy wooden craft takes tourists past unspoiled nature to observe wild ducks, cormorants, otters and beavers, and man-made landmarks such as the Pauline monastery and the Church of St Mary of the Snows in Kamensko.
