If you only have one day in Dubrovnik, I would suggest spending it on the City Wall Walk. It may be the highlight of your visit. It's a 2 km walk around the city with dramatic views of the coast and famous tiled rooftops. The wall was constructed between the 12th-17th centuries and surrounds the entire perimeter of Old Town. The walk can get crowded during the day, so try going early. We went when it opened, which was 8 am.
One of the best ways to get this iconic shot of Old Town Dubrovnik is to pack a drone in your suitcase. However, if you do not happen to have one, fear not! Follow along to see where you can get comparable (if not better) shots of this magnificent view of Dubrovnik.
If you're looking for a quick day trip from Dubrovnik, I would highly recommend visiting Lokrum Island. It's a quick 15-20 min boat ride from Dubrovnik and costs 120 Kunas, which includes a round trip and entrance into the nature reserve (i.e. the entire island!) Lots of unexpected sites and hidden treasures.
Feel free to explore the inside of Fort Royal, entrance is free.
The peacocks love the attention and will put on a show for you, just wait and see
The Iron Throne from Game of Thrones! No lines and no fees to take a picture, what more could you ask for?
We took a 3.5 hour ferry ride from Hvar to Dubrovnik (aka King's Landing). It was the one day out of our entire trip where it was rainy and cold for the majority of the day. Not a good day for traveling, but we made the most of it. From the ferry, we took the bus to Pile Gate, which is a drawbridge from the 1500s and the main entrance to Old Town Dubrovnik. It was our first glimpse into scenes filmed from Game of Thrones in Dubrovnik.
