Among the most emblematic natural and landscape site of the Armorique Geopark, the high sandstone cliffs of Pen Hir Headland and Tas de Pois Islets that extend it into the sea face the vastness of the ocean.
Its position was a long-standing fascinating landscape for men, as demonstrated by the archaeological settlement of Lagatjar nearby.
This site is today an important tourist magnet and has a significant potential to direct tourist flows to other sites of the Geopark for the purpose of a quality discovery.
