We run guided river days on the Zrmanja, Mrežnica and Una, covering kayaking, packrafting and whitewater rafting with resident guides who work those stretches through the season. Kit is fitted on the bank and a safety briefing comes first, then you paddle under people who hold International Rafting Federation licences and refresh first aid and river-rescue skills on a regular cycle.
The team grew out of Croatian river rafting in the 1990s and still staff the trips themselves, so the person you speak to before you book has usually been on the water that week. Bookings go through the Zagreb office on weekdays, groups stay small enough for the guide to look after everyone, and the day is paced around the river rather than a rushed timetable.
