The crossing
Seasonal fast catamarans link Dubrovnik's Gruž harbour with Mljet, run by Jadrolinija and Krilo (Kapetan Luka). Some sailings call at the Elaphiti islands or Korčula along the way, making this route part of a longer Dalmatian coastal corridor. The key stop is Polače, the port right beside Mljet National Park — aim for a sailing that serves it rather than Sobra alone.
Mljet National Park
The north-west third of the island is a national park built around two connected salt lakes — Veliko Jezero and Malo Jezero — with a small island monastery in the middle of the larger lake. Cycling paths ring the lakes, the water is clear enough for swimming, and the forest is dense and green. This is the main reason most visitors come to Mljet, and it is accessible on foot or bicycle from Polače.
Catamaran vs car ferry
- Catamaran from Dubrovnik (Jadrolinija and Krilo) — fast, passenger-only, seasonal, best for a day trip or foot-passenger stay.
- Car ferry from Prapratno (Jadrolinija) — the route for vehicles. Prapratno is on the Pelješac peninsula; drivers reach it from Dubrovnik via the bridge to Pelješac and the peninsula road. The car ferry arrives at Sobra.
Booking
Catamaran seats are limited and sell out in summer — book ahead, especially if you want a direct sailing to Polače. Check the current seasonal schedule carefully, as frequency drops sharply outside the main summer period.

Frequently asked questions
- How long is the ferry from Dubrovnik to Mljet?
- Fast catamarans reach Mljet in roughly 1 to 1.5 hours depending on whether they call at the Elaphiti islands or Korčula en route. Polače, by the national park, is the handiest arrival port.
- Can I take a car to Mljet?
- The fast catamarans from Dubrovnik are passenger-only. For a car, take the Jadrolinija car ferry from Prapratno (on the Pelješac peninsula) to Sobra instead.
- Which port is best for Mljet National Park?
- Polače, in the north-west, is right by the national park with its salt lakes. Sobra, the car-ferry port, is further east and about 30 minutes by road from the park.
