Mljet National Park

Mljet National Park covers the lush, forested western end of Mljet island and is one of the most beautiful natural escapes in southern Dalmatia. Its centrepiece is a pair of connected saltwater lakes – Veliko and Malo Jezero – surrounded by dense pine forest, with wonderfully clear water for swimming. In the middle of the larger lake sits the tiny St. Mary's Island, home to a 12th-century Benedictine monastery you can reach by a short boat ride included with your ticket. The park is perfect for swimming, kayaking, cycling and walking along the shaded paths around the lakes. Getting there: Mljet is reached by ferry or catamaran, typically from Dubrovnik or via an organised day trip. It makes a great full-day excursion, so plan an early start. Good to know: There is a park entrance fee (around €20–30 in season, less off-season). Bring water, swimwear, sun protection and good walking shoes, and consider renting a bike to cover more ground. Check ferry timetables in advance so you don't miss the return.
