The largest of the islands in the Gulf of Naples, Ischia rises out of the blue Tyrrhenian Sea like a rugged yet peaceful giant. This is the ideal spot if you’re looking to indulge in luxurious resorts, pristine beaches, natural thermal spas and mud baths, and of course, amazing Italian food. Arriving at the island by ferry from Naples, you’ll notice Castle Aragonese, which towers over the cobalt sea and is only connected to the rest of the island by a narrow paved walkway. With over 1,500 years to its name, it has been used both as a fortification and a convent.
