The highlight of Krka National Park, an hour-long loop follows boardwalks, connects 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. 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. Note that swimming is no longer allowed.

　　From the Lozovac entrance, buses (free with park admission) shuttle visitors from the large car park (also free) down a serpentine road to Skradinski Buk. Neither the free boats nor the buses operate from November to February, but in those months you can drive right down to the falls.
