Of all the Adriatic islands, Mljet may be the most seductive. Over 72% of the island is covered by forest and the rest is dotted by fields, vineyards and small villages. Mljet National Park occupies the island's western third and includes gentle coves and a pair of saltwater lakes. Most people visit this tranquil island oasis on excursions from Dubrovnik or Korula.
Plitvice Lakes National ParkThe extraordinarily beautiful pocket of wooded hills in this World Heritage site enclose 16 turquoise lakes that are connected by waterfalls and cascades. The mineral-rich waters carve through the rock, depositing tufa in continually changing formations. Wooden footbridges follow the rumbling water for an exhilaratingly damp 18km (11mi).
SolinThe ruins of the ancient city of Salona (now known as Solin), among the vineyards northeast of Split, are the most archaeologically important in Croatia. Salona was the capital of the Roman province of Dalmatia from the time of Julius Caesar until AD 614, when it was levelled by the Slavs and the Avars.
