Mljet
A long forested island with two saltwater lakes at its western end — a national park, quiet villages, and the best swimming in the region.
Why people stay in Mljet
Mljet is a long thin island (37km end to end) about 90 minutes from Dubrovnik by catamaran. Its western third is a national park built around two connected saltwater lakes, Veliko and Malo Jezero, ringed by a shady walking and cycling path and dotted with tiny stone chapels. On an islet in the big lake sits a 12th-century Benedictine monastery, reached by a small boat included in the park ticket ($25). Beyond the park, the rest of the island is a chain of small hamlets, olive groves, and beach coves.
Stay at least two nights if you’re coming — a day trip catches the park at its busiest. This suits swimmers, walkers, and quiet-seekers; the lakes are warmer than the sea, safe for kids, and largely empty by evening. Skip Mljet if you want restaurants, nightlife, or shops beyond a village grocer. The magic here is early-morning silence on a lake path with just cicadas.
The Hotel Odisej in Pomena (inside the national park at the west end) runs $180-$260 half-board with direct lake access. Small family guesthouses in Polače (the north ferry port) and Pomena offer $85-$130 rooms. Apartments in Babino Polje (the main village, mid-island) go for $70-$100 with kitchens and a car essential. For most visitors Pomena is the right base — steps to the lakes, small choice of restaurants. Avoid the east-island villages unless you have a car.

Getting around Mljet
Jadrolinija fast catamarans run from Gruž port to Mljet (Sobra or Pomena/Polače) 1-3 times daily depending on season, $12-$18, 90 minutes to Pomena. Faster than the car ferry (2.5 hours from Prapratno on Pelješac). A local bus runs between Sobra, Babino Polje, and Pomena, timed to some ferries. National park entry is $25 in summer, cheaper in shoulder season, free after 4pm.
Questions about Mljet
Overnight is better. Day-trippers arrive by 11am and leave by 4pm; if you stay you have the lake path to yourself at 8am and 6pm, which is the whole reason to come.
$25 in July/August is on the high side for what you get, but includes the monastery boat and lake path. Off-season is cheaper. If you’re on the island for 3+ nights, ask about a multi-day pass.
