Ploumanac'h lighthouse

The Men Ruz Lighthouse rises on a rocky point in Ploumanac'h, a small coastal village within the commune of Perros-Guirec, in the Côtes-d'Armor department of northern Brittany. It's one of the emblems of the Pink Granite Coast (Côte de Granit Rose), a stretch of shoreline famous for its striking red-pink granite boulders — the very rock the lighthouse is built on.

Where does the name come from?

Men Ruz comes from the Breton language and literally means "red stone" (men — stone, ruz — red). It refers directly to the color of the granite beneath the lighthouse: under sunlight, especially at sunset, the rocks along this part of the coast take on a deep reddish-pink hue. That color gave its name to both the lighthouse and, by extension, to the wider region known for the same rock formations.

What is the lighthouse used for?

Men Ruz functions as a navigation aid marking the entrance to Ploumanac'h harbor. For sailors and fishermen working this stretch of the Breton coastline, it's an important landmark — the surrounding waters are studded with jagged granite outcrops, making unmarked navigation genuinely hazardous. The lighthouse has long served this practical maritime-safety role, while also becoming one of the most photographed spots in the region.

How do you get to the Men Ruz Lighthouse?

Ploumanac'h sits on the Breton coast within the commune of Perros-Guirec, easily reached by car from regional towns such as Lannion or Saint-Brieuc. The best way to see the lighthouse is on foot, via the famous coastal footpath known as the Sentier des Douaniers (the old customs officers' trail), which runs the length of the Pink Granite Coast. Walking among the rock formations, with the lighthouse and nearby islets in view, is one of the most popular walking routes in this part of France.

What else is worth seeing nearby?

The lighthouse doesn't stand in isolation — it's part of a broader landscape of granite formations that has long drawn geologists, photographers, and walkers alike. The rocks themselves take on unusual, wind- and salt-eroded shapes, and their color shifts with the light throughout the day. It's worth timing a walk to see the lighthouse both in full daylight and at sunset, when the granite's color is at its most vivid.

When is the best time to visit?

Spring and early autumn offer good walking weather without the crowds of peak summer season. Summer brings more visitors and livelier cafés in Ploumanac'h, but also busier trails. Whatever the season, it's worth checking the forecast — strong ocean winds can make walking the exposed headland uncomfortable.
