One of the park’s most famous attractions is Veliko Jezero (Big Lake), a unique saltwater lake surrounded by pine forests and Mediterranean vegetation. Connected to the sea through a narrow channel, the lake creates a fascinating natural environment ideal for swimming, kayaking, and relaxation.

Nearby lies Malo Jezero (Small Lake), another beautiful saltwater lake known for its calm waters and tranquil surroundings. Together, these lakes form one of Croatia’s most extraordinary natural landscapes and are among the main reasons visitors choose a Mljet boat tour from Dubrovnik.

Located on a small island in the center of Veliko Jezero is the historic St. Mary’s Benedictine Monastery. Dating back to the 12th century, this picturesque monastery is one of Mljet’s most recognizable landmarks. Visitors can explore the island, admire its architecture, and enjoy spectacular views of the surrounding lakes and forests.
