Coastal scenery and hiking trails
The network of hiking trails includes 11 signposted routes through the Abers, dune areas and valleys. If you are looking for a route with a specific distance and duration, the circular route 3, “À la découverte de Spins,” is a good option: the walking route is six kilometres long and takes about two and a half hours. Check route conditions before setting out.

Goémonier heritage and seaweed
In the second half of the 19th century, Plouguerneau developed a significant Goémonier fleet. The Écomusée des Goémoniers et de l’Algue in Plouguerneau preserves Breton maritime heritage, particularly the history of the Goémoniers and the use of seaweed. The museum offers exhibitions, guided tours, workshops and events about harvesting and processing seaweed. As the visitor programme may change, it is advisable to check current dates and offerings in advance.
Seaweed harvesting is also part of the maritime tradition at Notre-Dame de Lilia church, where it is depicted as a scene from traditional parish life.
Lighthouses on Île Vierge
The 82.50-metre-high Île Vierge lighthouse is considered the tallest lighthouse in Europe and the tallest lighthouse in the world built from dressed stone. Beside it stands a smaller, 33-metre-high granite tower, which began operating in 1845. The tall lighthouse has 365 steps leading to the top; its interior is lined with 12,500 opaline tiles.
A guided tour of the small lighthouse includes boat transport from the Castel Ac’h slipway in Plouguerneau. Dates and availability may change, so check them in advance. Glaz Evasion excursions travel through the waters of Stagadon below the Île Vierge lighthouse. Seals may be spotted along the way—this is a possibility, not a guarantee.
Necropolis, bridge and more history
Iliz-Koz is a medieval necropolis in Saint-Michel, Plouguerneau. An interpretive trail with explanatory panels accompanies the visit; public visits take place under supervision. Check the current visiting arrangements before you travel.
The Pont Krac’h, also known as the Pont du Diable, crosses the Aber-Wrac’h and connects Plouguerneau with Lannilis at low tide. The crossing is subject to tidal conditions, so check local conditions before making plans. The bridge was restored in 2008 and rebuilt identically without modern materials.
Religious and local history can also be experienced at specific sites. Recurring celebrations for All Saints’ Day, Easter and Saint-Laurent are held at the Chapelle Saint-Laurent et Saint-Étienne. Keroudern is the birthplace of Michel Le Nobletz (1577–1652), a prominent figure in the evangelisation of Lower Brittany.
