Krka National Park, a short trip inland from Šibenik, protects the travertine waterfalls and canyons of the Krka River. The most famous cascade, Skradinski Buk, tumbles over seventeen steps amid lush greenery, with boardwalks, boat rides and the island monastery of Visovac to explore. Entry is ticketed with seasonal pricing, and the park is one of the most visited natural attractions in Dalmatia.
