Mljet Island

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 Korčula.

The highlights of the island are Malo Jezero and Veliko Jezero, the two lakes on the island's western end connected by a channel. Veliko Jezero is connected with the sea by the Soline Canal, which makes the lakes subject to tidal flows.

In the middle of Veliko Jezero is an islet with a Benedictine monastery; it was originally built in the 12th century but has been rebuilt several times, adding Renaissance and baroque features to the Romanesque structure.

The island is also ideal for cycling, and there are a few bike rental operators. Divers will not want to miss the opportunity to explore the old Roman wreck and the German torpedo boat offshore.
