Castle after castle strung along empty sand, with puffins and seals just offshore if the boat trip's running
There’s a stretch of this coast where you can see three castles at once without turning your head much, which tells you most of what you need to know about Northumberland’s priorities over the centuries. The designated area only covers 138 square kilometres, first recognised back in 1958, but it packs an unreasonable amount into that thin ribbon of dune and rock.
Bamburgh Castle is the one that ends up on the postcards, sat on its outcrop above a beach so big it makes people go quiet for a moment. Further along, Dunstanburgh and Newton Coast is the ruined version — no roof, no gift shop, just broken towers on a headland that looks better for the neglect. Out to sea, the Farne Islands run boat trips in season to see the grey seals hauled out on the rocks and, if timing lines up with the breeding colonies, more puffins than seems entirely plausible for a small patch of the North Sea.
Lindisfarne catches people out worst of all: the causeway floods twice a day, on a schedule that has nothing to do with convenience, and a dozen or more cars get stranded on it every year despite the tide tables being posted at both ends. Check the crossing times before setting off, not after. Seahouses makes a sensible base for boat trips out to the Farnes and does a reasonable line in fish and chips for afterwards. This coast catches wind straight off the North Sea with nothing much in the way to slow it down, so pack more than the forecast suggests — a bright morning can turn raw within the hour.
