Mljet Island, located in Croatia’s southern Dubrovnik-Neretva County, is a serene haven of unspoiled nature, ancient legends, and eco-friendly adventures. Covered in dense forests and surrounded by turquoise waters, the island offers a peaceful escape from the crowds. Whether cycling around its saltwater lakes or exploring the mythical Odysseus Cave, Mljet delivers a truly off-the-beaten-path experience.

What Makes Mljet Island Unique
Mljet Island is often celebrated as Croatia’s greenest island. Nearly 90% of its surface is cloaked in dense pine forests, and the western half is protected as Mljet National Park. This rich natural landscape makes it a haven for nature lovers, history enthusiasts, and outdoor adventurers.
Unlike more crowded Dalmatian destinations like Hvar or Korčula, Mljet remains blissfully untouched by mass tourism. Visitors come here to slow down, breathe deeply, and immerse themselves in the soothing pace of island life.
Mljet National Park: Nature’s Masterpiece
Located in the western part of the island, Mljet National Park is a stunning mosaic of forests, lakes, and walking trails. Two saltwater lakes, Veliko and Malo Jezero, dominate the park. These lakes connect to the Adriatic Sea through a narrow channel, creating a unique tidal ecosystem.
Top Things to Do in Mljet National Park
Cycle around the lakes: A scenic 10 km bike trail loops around Veliko Jezero.
Visit St. Mary Islet: A tiny island in the middle of the lake with a 12th-century Benedictine monastery.
Swim or kayak: Calm, warm waters are perfect for paddling and swimming.
Hike to Montokuc: The highest point in the park offers panoramic views over the lakes and the Adriatic.
The park entrance fee includes the boat to St. Mary and an electric mini-train ride. Adult tickets cost €25 in high season (June–September) and €15 in low season (October–May). Children aged 8–18 pay €8/€5 depending on the season, and kids under 8 enter free.
Odysseus Cave Mljet: Myth Meets Adventure
According to legend, Odysseus was shipwrecked here and held captive by the nymph Calypso. Today, you can swim or paddle to this sea cave near the village of Babino Polje. Crystal-clear water, dramatic cliffs, and echoes of ancient myths make this a must-see.
The best time to visit is midday when sunlight beams into the cave, illuminating the water with a magical blue glow.
Saplunara Beach: A Hidden Gem on the Eastern Shore
Unlike most Croatian beaches, Saplunara offers golden sand and shallow turquoise water. Located on the southeastern tip of the island, it’s ideal for families and those craving a classic beach day.
There are two main beaches: Velika and Mala Saplunara. Both are backed by pine forests and offer basic amenities and local konoba-style restaurants.
