Of course you are still in South Italy so you will hear italian yelling on their scooter ( hello cliché that happened to be true ) but you will enjoy the calm of Procida. Less noisy than Naples and less crowd than Capri, this island is the perfect mix between italian charm and the peace you can find near the sea.
One of the many advantage of Procida is that you can visit it completely by foot. Indeed, its only 4 km long. Of course, if you don’t want to, you will find some buses at the main port to bring you in key places.
