Placed on a tall cliff, the oldest city of Krk island, Vrbnik, holds home to the narrowest street in the world! But, according to many, that is not what made this little town famous. It is the local wine called Vrbnicka Zlahtina, one of the finest Croatia has to offer! Vrbnik cave is another interesting site to visit. Even though, not huge in size and only 17m deep, the ceiling hole through which the outside light shines makes it extremely attractive!
