Located just 600 meters from Dubrovnik, the island of Lokrum is pretty hard to miss. If you've got time in your Dubrovnik sightseeing itinerary, hop aboard the short ferry ride to this fascinating island. 

In addition to the superb views over the Old Town of Dubrovnik, there are a few interesting attractions you'll find here worth exploring (and usually with few if any crowds).

Head first to Fort Royal Castle, a fortification constructed by Napoleon's troops to defend the harbor city.
