One of three islands off the coast from Naples, Ischia is the largest, although it is still considered a bit more off the beaten path than it’s historically popular sister, Capri. The two main ports on Ischia are the city of the same name and the city of Forio, both of which have regular boat and ferry transport from the mainland. There are also other towns that provide accommodation, food, and more if you’re exploring the area.
Speaking of adventure (weren't we?), Ischia has plenty to do; from trekking up Monte Epomeo from the town of Fontana to lounging on the many beaches of volcanic sand to circumnavigating the beautiful coastline in a boat to relaxing in thermal spas. First off, Epomeo towers above the rest of the landscape, providing fantastic views of the surrounding islands and sea, and is a stage for the island's plant biodiversity.
The beach most worth your time is Cartaromana, which is most approximate to the spectacle that is Castello Aragonese. Relax in the thermal spas of Cartaromana and then cross the stone bridge to this castle on its own rocky, island perch. Entrance to the castle, built in 474 BC, is worth the 10 Euro for the unique antiquity and landscape. Another beach of note is the highly-frequented dell'Isola in Forio.
Also worth noting are the many lovely villas and public gardens on the island, including Villa La Colombaia and Giardini Ravino in Forio.
If you travel to Ischia, don’t be surprised if you don’t want to go anywhere else; there aren’t many places in Italy with so much to see and do without so many tourists to muddle it up. Enjoy it while you can!
