Pnte du Raz is not just any cap at any ocean. It is the westernmost point of the entire Bretagne. Also, it is the wildest point where land meets ocean. Even during a normal day, waves are about 2 metres high, at least.
Baie des Trépassés
Going back from the cap through the village of Plogoff the road will lead you back to the bay that connects Pnte du Raz with Pnte du Van, that place is called Baie des Trépassés. If you are keen to see breakwater coming into the bay, here is your place to be.
