Durdle Door, DorsetPart of the Jurassic Coast World Heritage Site, Durdle Door is one of the most recognisable natural landmarks in England. The view of the striking rock formation is most impressive from on top of the cliffs, but an equally enticing experience has to be swimming under the archway on a warm summer’s day. There is a path to the beach from Lulworth Cove that offers dramatic views on the way down.
