Dubrovnik Croatia has lots to offer, both historically and the natural beauty. Situated on the Adriatic Sea, with the Dubrovnik River flowing through the City and out to the sea, yields spectacular views and water opportunities. Dubrovnik's Old City is surrounded by walls that were built between the 13th and 17th centuries. The walls provided protection from the Venetians and other potential intruders. You can walk on top of the walls, typically it takes about 45 minutes to cover the 1.5 miles. We'll do that for you and show you some of the highlights in a few minutes. Now Croatia has joined the European Union and uses the Euro for its currency. Croatia has struggled over time to gain its independence. Now independent, it has lots to offer.
