The tourist-thronged city of 60,000 is separated from the Swedish city of Helsingborg by a 20-minute ferry ride. Just an hour by train from capital Copenhagen, Helsingor basks on Denmark's North Riviera, surrounded by golden beaches and dense forest. The UNESCO-designated, Dutch Renaissance-style Kronborg Castle boasts the impressive claim of having provided the setting for Hamlet. A charming town of half-timbered houses, cobblestone streets and castles, Helsingor is easily explored by bicycle.
