Capri’s Roman villas and cliff paths record imperial occupation and later international tourism, but the island remains an inhabited municipality with scarce space, water, transport capacity and protected natural areas.
Ischia’s geology supports thermal systems, steep landscapes, agriculture and continuing seismic and volcanic monitoring. Castles, ports and gardens sit within an active geological field rather than on a generic resort island.
Procida’s Terra Murata, Corricella and harbours preserve dense architecture and maritime traditions under strong seasonal pressure. Ferries and sea state govern all three islands, so they should be visited on separate days rather than combined into a race.
Choose one island per day, verify the exact ferry and return sailing, then use local buses or walking routes within current capacity and weather; never treat the bay as a guaranteed timetable.
