Where this list comes from
Every castle here is listed because a real visitor described the sea, the coast, or clifftop and sea views in a Google review. It's a list built from what visitors actually saw and said, not from a map, so it captures the castles people genuinely experience as coastal.
Always check before you book
Coastal castles can mean exposed cliff paths and weather-dependent access - some island and clifftop sites are tide- or ferry-dependent. Check the castle's own page (linked from every entry) and the forecast before you set out.
