Take a dip into the Adriatic Sea
There's no doubt that Croatia is all about its coastal cities. Experiencing towns like Split, Dubrovnik or the heart-shaped peninsula of Istria during the summer is fabulous. The food is great and swimming in the transparent waters is heavenly. Discover the capital of Zagreb for a vibrant nightlife or go to Rijeka where Tito's old boat is stationed. It is now a museum. For a natural retreat explore the National Park Plitvice Lakes—a UNESCO world cultural heritage site.
