All around, the rugged coastline reveals reefs, coves, and rocks sculpted by the elements. This rugged landscape is among the most beautiful in the Côte d’Armor and can be admired from the trail that runs along the shore.

Castel Meur, the house among the rocks

Built in 1861, it was positioned at this exact spot to protect it from the westerly winds that relentlessly sweep across the headland. This house nestled between the rocks has become the symbol of the Gouffre de Plougrescant and one of the most photographed sites in Brittany.
