The crossing

Seasonal fast catamarans link Dubrovnik's Gruž harbour with Mljet, some calling at the Elaphiti islands or Korčula along the way. Aim for a sailing to Polače, the port right beside Mljet National Park.

Mljet National Park

The north-west third of the island is a national park built around two connected salt lakes, with a tiny island monastery, cycling paths and swimming spots — the main reason most visitors come.

Catamaran vs car ferry

Catamaran (Dubrovnik–Polače/Sobra) — fast, passenger-only, seasonal, best for a day trip or foot-passenger stay.
Car ferry (Prapratno–Sobra) — Jadrolinija route for vehicles, reached by driving up the Pelješac peninsula from Dubrovnik.

Booking

Catamaran seats are limited and sell out in summer — book ahead. Compare operators and sailing days, as frequency drops sharply outside the main season.
