It is listed as a world heritage site for a reason. It is unquestionably picturesque and most likely quite unique in the world, which is of course, what draws the masses of tourists.

After a bit of touring around on the first day, we spent the rest of our time there enjoying a beach holiday.
My favorite part was lying on the pebble beach, gazing out into the Mediterranean Sea and having espresso delivered to me!
La dolce Vita!
