Mljet
A natural retreat in the southern Adriatic — Croatia's greenest island, shaped by forests and saltwater lakes
About Mljet
Mljet is one of Croatia's greenest and most tranquil islands, often described as a natural retreat in the southern Adriatic. Covered in dense pine and oak forests and surrounded by clear waters, Mljet suits travellers looking for quiet, outdoor activities and unspoilt landscapes.
The island's defining feature is Mljet National Park (Nacionalni park Mljet), which protects its western third and is known for two saltwater lakes, sheltered coves and shaded walking trails. With very limited development and a slow pace of life, Mljet offers a clear contrast to the busier Dalmatian hotspots.
With forest covering roughly 72% of its surface, Mljet is one of the most densely wooded islands in the Mediterranean.
A Glimpse into Mljet's History
Legends, monks and quiet isolation
Mljet has been inhabited since ancient times and is often linked to legends, including the myth that Odysseus was shipwrecked here and stayed in what is now known as Odysseus' Cave (Odisejeva špilja) on the island's south coast. Over the centuries, Mljet remained relatively isolated, which helped preserve its natural environment and traditional way of life.
In the 12th century, Benedictine monks settled on a small islet inside the Great Lake (Veliko jezero), building a monastery that became the spiritual and cultural heart of the island. Today, Mljet's history is closely tied to monastic life, forestry and fishing, with nature always playing the central role.

Frequently Asked Questions about Mljet
The main gateway is Dubrovnik, with year-round car ferries to Sobra and seasonal passenger catamarans to Polače and Sobra. In summer there are also day-trip boats and connections from Korčula and the Pelješac peninsula. Journey time from Dubrovnik is about 1.5–2 hours by fast catamaran or longer by car ferry.
Yes, especially if you are interested in nature, walking and swimming in calm, clear water. Mljet National Park with the Great Lake and Small Lake, the Benedictine monastery on St Mary's Island and the quiet southern beaches around Saplunara are the main reasons to come. Travellers looking for nightlife or packed old towns will prefer Hvar or Dubrovnik.
One full day is enough to see the core of Mljet National Park — a walk or cycle around Veliko jezero, the boat to St Mary's Island and a swim in one of the lakes. Two or three days allow time to explore the southern beaches at Saplunara, visit Odysseus' Cave by boat and experience the island's slow evening pace.
Yes. Both Veliko jezero (Great Lake) and Malo jezero (Small Lake) are saltwater lakes connected to the sea, and swimming is allowed in designated areas. The water is usually warmer than the open sea in summer and particularly calm, which makes the lakes popular for families and less confident swimmers.
Yes. A national-park ticket is required to enter the western part of the island, and the price includes the boat transfer to St Mary's Island with the monastery. Tickets can be bought at park entrances in Pomena and Polače. If you are staying inside the park area, check with your accommodation about multi-day or resident access.
