The pine-covered island of Mljet has been turning heads for centuries – counting Prince Charles and ancient Greek poet Homer as fans. The catamaran will drop you off in Pomena – a quaint harbour village, home to around 50 residents. You’ll have the afternoon to wander the thick forests and saltwater lakes of Croatia’s greenest isle. Most of the north-western coast is covered by Mljet National Park, but the highlight is a pair of turquoise-tinted lakes. Stroll along the water, shaded by pines, or rent a kayak to reach more secluded spots. Then, catch a boat to the tiny islet of Sv Marija, where you can dine in a former Benedictine monastery. If you’ve got your walking shoes on, you can also hike up Montokuc. It’s the highest peak in the park, so you’ll get a bird’s eye view of the rugged isle. After, hop back on the boat for a cruise down the coast.
