Hotels on Croatia's Adriatic coast stretch from Istria across the Kvarner Bay to Dalmatia. The beaches are mostly pebbly in naturally beautiful, rugged bays, fringed by Mediterranean landscapes of pine trees, cypresses and pines. In old towns nestled by the sea, culture buffs will encounter medieval fortresses and stone city walls. In addition, narrow, winding streets under red roofs. First and foremost, imposing Dubrovnik in the south and charming Rovinj in the north, with houses that seem to float on a round peninsula directly above the sea.
