About

The Sentier des Douaniers, or the Customs’ Path, is a 25‑kilometre coastal trail that winds through the extraordinary Côte de Granit Rose in Perros‑Guirec, Brittany. The path follows the legacy of 18th‑century customs officers, who once patrolled the shores from granite stone guardhouses. Today, hikers can traverse a landscape of pink granite outcrops, sweeping dunes, and rugged cliffs, all while enjoying uninterrupted views of the Atlantic. The trail is stroller‑friendly in many sections, making it an excellent choice for families, while seasoned trekkers appreciate its moderate elevation changes and the opportunity to spot local wildlife. A guide‑free walk typically takes three hours, but many visitors choose to explore smaller loops or combine the path with a stroll along the scenic Ploumanac’h coast. Whether you’re capturing sunset over the Mean Ruz lighthouse, photographing the crackling “landes”, or simply breathing in the salty air, the Sentier des Douaniers offers an accessible, unforgettable experience for all ages.
