The highlight of Krka, this hour-long loop follows boardwalks connecting little islands in the emerald green, fish-filled river and terminates at the park's largest waterfall. Skradinski Buk's 800m-long cascade descends by almost 46m before crashing into the lower lake, which is a popular swimming spot. Nearby, a cluster of historic mill cottages have been converted into craft workshops, souvenir stores and eateries. The whole area gets insanely busy in summer.
