Dubrovnik is stunning seaport city located right on the Adriatic Sea and surrounded by impressive fortifications known as the City Walls. Walking the City Walls is a popular tourist activity, but seeing the famous walls from the water offers an entirely new perspective. 

Sea Kayaking around the city allows you to discover amazing views of the city walls, explore nearby Lokrum Island, snorkel or swim in the crystal clear water, and paddle through numerous hidden caves. If you're brave, you can also do some cliff jumping from the rocks surrounding the city. 

There are numerous kayak tour companies located at Pile Gate. I took a tour with Adventure Dubrovnik, and loved it. You can rent kayaks from Pile Gate as well.
