Tintagel has been attracting people on holiday for generations thanks in part to its historic sites including, of course, the English Heritage-listed castle. The ruins of this sprawling, 1,500-year-old castle, with links to the legendary King Arthur, are split between the mainland and a headland. A visit includes the opportunity to visit the beach below, and if the tide’s out, Merlin’s Cave too. You can also explore different options for camping near Tintagel on Hipcamp.
