A few miles to the west of Crozon, Dinan headland commands a fine view: to the left is Cape Chèvre, the Cornouaille coast and Pointe du Raz promontory; to the right are the Pointe de Penhir and the Tas de Pois. As you skirt the cliff to the right, you will see the "castle" of Dinan, a huge craggy rock at the edge of which is a natural arch. A path cuts through the natural arch and visitors can explore this mass of rocks.
