About Ischia

Ischia is the Bay of Naples' green island—thermal parks, vine-covered hills, and the Aragonese Castle on its own rocky islet connected by causeway. May to June and September to October bring warm Gulf water for Sant'Angelo coves, Negombo thermal gardens, and hikes to Monte Epomeo without August's ferry lines from Naples or Pozzuoli. July and August fill every hotel and beach club; book spa slots ahead. Winter stays mild and cheap for thermal focus, though some seasonal restaurants close and sea swimming cools quickly after October.
