Hotels in Ischia Island, Italy

Ischia Island sits in the Tyrrhenian Sea off Naples, Italy, with a Mediterranean climate that brings mild winters around 50°F (10°C) and hot summers averaging 86°F (30°C). It's world-famous for its volcanic thermal spas like the Poseidon Gardens, where you can soak in naturally heated pools year-round. In summer, hit the black-sand beaches of Maronti or hike Mount Epomeo for views of the bay, while spring and fall offer cheaper spa deals and fewer crowds for exploring the Aragonese Castle's 15th-century history.
