Plitvice Lakes National Park

A forested island ten minutes by boat from the old harbour, with a botanical garden, a monastery ruin and a saltwater swimming lagoon.

The hill directly behind Dubrovnik, reached by cable car or a switchback path, looking down on the walled town and the islands.

A fourth-century Roman palace complex that became the core of Split, with an intact peristyle, cathedral bell tower and vaulted basement halls.

A pine-covered headland on the edge of the old town, with stepped paths to viewpoints, chapels and small rocky swimming coves.

The Krka river drops through a series of travertine cascades inside a limestone canyon between Šibenik and Knin, with Skradinski Buk the largest and most visited set. Boardwalks loop around the falls, and boats run up the flooded river gorge to the monastery island of Visovac. Swimming below the main falls is no longer permitted.

The widest set of falls on the Krka, seventeen steps dropping about 45 metres, circled by a boardwalk from the Skradin boat landing.
