Lying inland from Zadar in northern Croatia, the River Zrmanja rises in the Dinaric Alps and runs for 44 miles (70 km); the bulk of its course lies within the Velebit Nature Park before it empties in the Novigrad Sea after passing the cute, pastel-colored town of the same name built along its meandering banks. Along with its tributary the Krupa, the upper reaches of the Zrmanja are one of the country’s hottest spots for rafting and kayaking through its spectacular limestone canyons – in parts 656 feet (200 meters) deep – and underneath its tumbling cascades. The most spectacular falls are Veliki Buk, a crescent-shaped mini-Niagra where the pristine waters hurls itself 65.5 feet (20 meters) in two steps over a limestone cliff face; a popular hike to the falls starts at Muskovci, with amazing views over the lush Zrmanja river valley.
An hour’s drive east from Zadar. No previous experience is necessary for rafting trips; children must be aged six to participate and all participants must be able to swim. Safety equipment provided.
