Mljet in Croatia: National Park, Salt Lakes and Island Nature

• Mljet lies off the coast of southern Dalmatia and is best known for its national park in the west.
• The salt lakes Veliko Jezero and Malo Jezero, along with the island of Sveta Marija, define the national park area.
• Ferries dock at Sobra; depending on the route, catamarans reach Pomena or Polače.
• The national park has entrances at Pomena, Polače and Vrbovica; from November to April, visits are possible only by prior arrangement.
• The forest, shores and protected habitats call for care and respect for park rules.
• Dubrovnik, Hvar, Brač and other islands are separate legs of a trip, each requiring its own ferry crossing.

The national park in the west of the island is its best-known highlight. Trails around Veliko Jezero and Malo Jezero wind through Mediterranean scenery. From Pomena, a footpath takes about 15 minutes to reach Malo Jezero; the park gives a walking time of ten minutes for the trail around the Small Lake. The park boat to the monastery island of Sveta Marija departs from Mali most. From Polače, a hiking trail leads to the Montokuc viewpoint and continues via Soline to the Great Lake; the return walk from Pristanište to Polače takes about 40 minutes. Water, sun protection and sturdy shoes are essential on these trails.

The island of Sveta Marija, with its church and former Benedictine monastery, lies in the Great Lake. The park boat departs from Mali most near Pomena or from Pristanište near Polače; a circular route around the lakes can connect both landing points via walking trails. In high season, an early start shortens waits for trails and boat connections.

Mljet is more than just its national park. Small towns, coves and roads through the landscape offer a different feel from the busier coastal towns. For a peaceful stay, choose accommodation close to your main destination: Pomena and Polače are near the park entrances and lakes, while Sobra is the car-ferry port, outside the western park area. If you want to swim, hike and visit the park, staying near your chosen starting point saves long drives across the island.

Mljet is in Dalmatia. Dubrovnik can serve as a mainland and cultural stop before or after Mljet. For comparisons with other islands, see Hvar, Brač and the information about the islands of Croatia. Mljet is an island leg within a trip around Croatia.

Jadrolinija’s car ferry connects Prapratno on the Pelješac peninsula with Sobra; the crossing takes about 45 minutes. Catamarans from Dubrovnik, as well as services via Brač, Hvar and Korčula, call at Pomena or Polače, depending on the timetable. This brings foot passengers closer to the western national park area, while Sobra is the arrival point for visitors bringing a car. Services vary by season, day of departure and weather.

A car can be useful on Mljet, but it is not necessary for every stay. Drivers can take the island road from Sobra to Pomena, Polače or Vrbovica; the park lists parking in Vrbovica near the Great Lake. Those travelling on foot can choose to arrive by catamaran at Pomena or Polače. Pack water, sun protection and sturdy shoes for the trails to the lakes and viewpoints.

The ideal length of stay depends on what you want to do. A full day can be enough for the national park if you arrive early and allow plenty of time for the return journey. Two or more nights also leave time for swimming, exploring smaller towns and adjusting plans if the weather changes. Mljet is especially rewarding for travellers who don’t want to squeeze nature experiences between frequent changes of location.

Choosing accommodation in a suitable location on Mljet and in Dalmatia depends on your arrival port and plans for the park: Pomena or Polače save time getting to the salt lakes, while Sobra is convenient for arriving by car. For a day trip, the boat journey or crossing the island, park trails and return trip all need to fit into the same schedule.

The western part of Mljet is a natural area and excursion destination with its own rules, designated as a national park. If you have only a few hours, choose one clear focus and allow for the crossing and return to the port.

On a route through Dalmatia, foot passengers can reach Mljet from Dubrovnik or, depending on the timetable, via Hvar and Brač. When combining several Croatian islands, each crossing is a separate leg of the journey. Every additional island means its own schedules and waiting times. Mljet is therefore better suited to a quiet overnight stay or a carefully planned day trip than to a tightly scheduled island-hopping itinerary.

For getting there, the car ferry allows you to bring a vehicle, while catamarans reach Pomena or Polače. Planning your trip should include time for the park entrance, hiking trails and boat ride. Sturdy shoes, water and sun protection are essential for a safe island hike on forest trails and by the lake.
