Discover Plouguerneau: Coastline and Maritime Heritage

Plouguerneau combines a long coastline with walking trails, maritime history and archaeological sites. This offers various reasons to plan a trip: you can explore the landscape on foot, learn about the history of the seaweed industry or visit individual cultural sites.

Coastline and Walking Trails

The 45-kilometre coastline includes cliffs, headlands, peninsulas and sandy beaches. There are 11 marked walking trails in the area, running through estuaries, dune areas and valleys. For a walk with a specified distance and duration, the circular Route 3, “À la découverte de Spins,” is a useful guide: it is six kilometres long and takes about two and a half hours on foot. Circular Route 8bis offers a different landscape, passing through wetlands considered particularly rich in biodiversity. Ground conditions there may change with the seasons. Check route conditions before setting out.

Seaweed and Maritime Heritage

In the second half of the 19th century, Plouguerneau developed a significant goémonier fleet. A range of attractions draw on this history: the ALGAE cultural and scientific centre is dedicated to discovering and promoting seaweed. It offers workshops, nature outings, talks and immersive experiences. The Écomusée des Goémoniers et de l’Algue preserves Breton maritime heritage, particularly the history of the goémoniers and the use of seaweed. Its programme includes exhibitions, guided visits, workshops and events about harvesting and processing seaweed. If you are planning your trip around a particular guided tour, workshop or event, check the dates in advance; visitor offerings may change.

Lighthouses of Île Vierge

The Île Vierge lighthouse is 82.50 metres tall and is considered the tallest lighthouse in Europe and the tallest lighthouse in the world built from dressed stone. Its tower has 365 steps and is lined inside with 12,500 opaline tiles. Beside it stands a smaller granite tower, 33 metres tall, which began operating in 1845. The two structures offer different historical and architectural details to explore when visiting the lighthouse complex.

A guided tour of the small lighthouse includes boat transport from the Castel Ac’h slipway in Plouguerneau. Schedules and availability may change; check the details in advance. For another perspective on Île Vierge, Glaz Evasion excursions travel across the waters of Stagadon below the lighthouse. Seals may be spotted along the way.

Archaeology, Churches and Bridges

Iliz-Koz is a medieval necropolis in Saint-Michel, Plouguerneau. An interpretation trail with explanatory panels accompanies the visit; public visits are supervised. Check the visiting arrangements before you arrive. The church of Notre-Dame de Lilia also preserves a scene from maritime daily life: seaweed gathering is depicted there as part of the parish’s traditional way of life. Keroudern is the birthplace of Michel Le Nobletz (1577–1652), a significant figure in the evangelisation of Lower Brittany.

Pont Krac’h, also known as Pont du Diable, crosses the Aber-Wrac’h and connects Plouguerneau with Lannilis at low tide. The crossing depends on the tides, so check local conditions in advance. In 2008, the bridge was restored and rebuilt identically without modern materials. The chapels offer another historical connection: recurring celebrations for All Saints’ Day, Easter and Saint-Laurent take place at Chapelle Saint-Laurent et Saint-Étienne. Chapelle Notre-Dame de Délivrance was built in 1845.
