Fodor's Expert Review Lindisfarne Castle

Reached during low tide via a causeway from the mainland, this castle appears to grow out of the rocky pinnacle on which it was built 400 years ago, looking for all the world like a fairy-tale illustration. In 1903, architect Sir Edwin Lutyens converted the former Tudor fort into a private home that retains the original's ancient features. Across several fields from the castle is a walled garden designed by Gertrude Jekyll. Opening times are notoriously changeable—especially on Monday outside midsummer—and are always dependant on weather and tides, so it's best to call ahead.
