With highlights dotted along the sparkling Adriatic, Croatia offers historical discovery and seaside scenery in abundance. In this wide-ranging Croatia tour, we witness 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.
