With highlights dotted along the sparkling Adriatic, Croatia offers historical discovery and seaside scenery in abundance. In this wide-ranging Croatia tour, we head inland to explore the pretty streets and squares of its compact capital, Zagreb, before witnessing the natural beauty of the emerald Plitvice Lakes. We tour Šibenik’s incredible limestone-and-marble domed cathedral and Split's walled Roman palace. Finally, we head for the exquisite old town of Dubrovnik, with its white-stone buildings and red-tiled roofs set against the ink-blue sea.
