The western portion of the Adriatic island of Mljet, located in southern Croatia, is home to the Mljet National Park.

Its territory spans over 5,300 hectares (53 km2) and comprises the western portion of the island, Veliko Jezero, Malo Jezero, Soline Bay, and a sea belt 500 meters wide from the most notable cape of Mljet.
The towns of Goveđari, Polače, and Pomena, as well as Veliko jezero with the Isle of St. Mary and Malo jezero, are in the park's center.
The inaugural declaration of the Park was made on November 11, 1960.You can trek up the hills (200 m) to gain views of the breathtaking landscape from the hills above the Mljet Park and seashore. Pomena's shopping market is the ideal location if you need to buy for necessities in the park.The communities of Pomena and Polače provide access to the park from either the north or west shore. Visitors must pay for their admission at a kiosk in Polače or Pomena, even though there isn't an official entrance to the National Park per se. Both kiosks have maps of the Park and informational pamphlets and leaflets.Admission costs:

Veliko and Malo Jezero (Large and Small Lakes) are two saltwater lakes that are adjacent to the vast region of Mljet National Park. The Lakes are roughly 4 kilometers long. Melita (Sveta Marija), a little island or islet in the center of the Large Lake, is home to a sizable structure that was once a Benedictine monastery and was constructed in the 12th century (see photo above). The building that once housed the monastery is now a café/restaurant. There are boats that sail to the small island from both sides of the lake. You can also visit Plitvice Lakes National Park, which is located in northern Croatia and features lakes and a small islet.A national park has been established on the western third of the island of Mljet. It is mostly covered in dense forest and is centered on two connected turquoise saltwater lakes, one of which contains an islet topped by a Benedictine abbey from the 12th century that is accessible by taxi-boat.

The park, which is well-liked by those who enjoy the outdoors, has several activities, such as strolling along the many routes that wind through the forest. Additionally, there is a nine-kilometer track that around the lakes, which is perfect for mountain biking or strolling. Swimming and canoeing are also popular pastimes in the area (you can rent kayaks to explore the lakes).There is only one hotel on the island, although there are several respectable campsites and rooms that local families rent to tourists in the summer. From Dubrovnik, Mljet is accessible by catamaran or ferry.

You can ride a bike or take a walk along the nice, shaded trails that surround both lakes. Additionally, you can rent a bicycle to get around Pomena, Polače, and Mali Most.
If you would like, you can rent a kayak at Mali Most, which is the spot where two lakes are connected by a tiny channel, and paddle around both lakes. Kayaking is also permitted.

Since the water at the park is significantly warmer than the island's beaches, swimming and tanning are enjoyable activities. It takes roughly forty minutes to walk from Polače to Veliko and Malo Jezero, crossing the valley and going through a wood.

Walking from Pomena to Malo Jezero and Small Bridge (Mali Most), where regularly scheduled boats go to Sv. Marija (Melita) islet, takes roughly ten minutes each. Both trails go through lovely pine and bay woodlands and are well-marked.
