In mid-season the best time to visit Dubrovnik is sunset, when you will not only miss the cruise liner guests and the midday heat but will be treated to the most amazing views as the sun sets behind the town, over the islands and mountains.
You can only enter the town on foot, through the main, Pile Gate, or, if you have used the cable car, the Buža Gate. Both lead you through medieval charm along the marble street, Stradun, that runs the length of the city and is lined with 17th century buildings. Either side of Stradun are steep lanes brimming with vibrant cafes, restaurants and smart boutiques.
On arriving in the city walls there are guides to take you through the city and bring it to life. Churches and museums are on every corner, most have a small entrance fee.
