The 72.5km Krka River and it’s wonderful waterfalls, one of which is shown in this picture, define the landscape of the Sibenik Knin region and are the focus of Krka National Park. According to the Lonely Planet guide the Krka waterfalls are a karstic phenomenon in that over millennia, river water has created a canyon(up to 200m deep) through limestone hills, bringing calcium carbonate with it. Apparently mosses and algae retain the calcium carbonate and encrust it in their roots. These growths creates barriers in the river that produce these spectacular waterfalls. We went for a wonderful hike here today and all throughout you heard that fabulous sound of the waterfalls. At the end there were women selling figs and nuts so that became our lunch.
