You can pick a contemporary guide about Ischia, or an old one, but both will surely describe you the sites that you shouldn’t miss when visiting this heavenly resort. Make your pick:

- The oldest guide found dates from1892: Hand-book to Naples and its environs: Pompeii, Vesuvius, Castellammare, Sorrento, Paestum, Amalfi, the Islands of Capri, and Ischia, by Luigi Piale.

- From1945, take a look at Summer Islands: Ischia and Ponza by Norman Douglas.

- From 1974: Naples: Capri, Ischia, Sorrento by Edoardo Bonechi.

If you want a recent one, take a look at:

- Hunter Publisher’s guide: Adventure Guide Naples, Sorrento, the Amalfi Coast: Capri, Ischia, Pompeii, Positano. You’ll find the list of all spas, art events, dining options, hotels, shopping circuits and lots of outdoor activities (which seem to be this editor’s trademark).

- Frommer’s Amalfi Coast with Naples, Capri & Pompeii by Bruce Murphy and Alessandra de Rosa. As every Frommer guide, it gives the insight into the different locations from the direct knowledge of local writers.

- Two guides worth mentioning written by local writers and entities are: Ischia. Procisa. Capri by Nana Claudia Nenzel and The Heritage Guide Naples: The City and Its Famous Bay, Capri, Sorrento, Ischia, and the Amalfi Coast Down to Salerno (Heritage Guides) by Touring Club Italiano and Touring Club of Italy.
