The Krupa River is an unknown pearl of karst, an oasis surrounded by rock. It is one of the least known, yet one of the most beautiful rivers of Croatia. It is only seven kilometres long, but has much more to offer than a ten times longer river, often degraded into a lifeless canal. The view from the edge of its deep canyon that carved itself into Dalmatia’s karst waterless plateau is breath-taking: the glistening waterfalls that tumble down to the river’s crystal clear water takes on a deep greenish hue.
