Dubrovnik, Croatia – September 20 – 23, 2014 Dubrovnik is likely the most popular tourist destination in Croatia and after spending a couple of days in the area, it is easy to see why. Dubrovnik and its walled Old City is spectacular, perched on the Adriatic Sea with Srd Mountain providing a backdrop. It is a popular destination for Mediterranean cruises so when that ship docks, you can expect an influx of thousands of tourists!
