Le Chemin Vert du Petit Caux : A nature walk along a former railway line

Looking for a peaceful and scenic escape? Starting in the town of Eu, the Chemin Vert du Petit Caux takes you on a journey through nature and heritage along a former railway line converted into a greenway. Over 7 km of landscaped path, walk, cycle or ride through a green haven where local flora and fauna thrive in complete tranquillity.

Along the way, admire the impressive viaducts offering beautiful views over the valley and surrounding countryside. Railway remains scattered along the route recall the history of this line, which once connected Eu to Dieppe until 1972.

Interpretation panels placed along the greenway reveal the railway past of the site and share the secrets of this unique heritage.

On foot, horseback or mountain bike, this shaded trail is a peaceful escape—ideal for a family outing or a relaxed discovery of Normandy’s preserved landscapes.

The Beaumont Loop: Following the Footsteps of an Ancient Past

Fancy a hike combining rolling viewpoints, mystical woodland and ancient remains? The Beaumont Loop takes you through a preserved landscape of forests and hillsides, offering striking views over the surrounding valley.

The route begins in Saint-Pierre-en-Val, where the village church reveals a beautiful 17th-century altarpiece and an elegant carved cornice. Further on, you’ll pass La Ferme de la Poterie, once home to Cadoudal, a key figure of the Chouans.

Next comes the Bois l’Abbé, a green sanctuary crossed by shaded forest paths. But this woodland holds more than meets the eye: it is home to the archaeological site of Briga, a former Gallo-Roman city whose extensive remains bear witness to a fascinating past. In summer, the Vert Ponthieu becomes a lively excavation site where archaeologists and history enthusiasts come together to explore this exceptional heritage.

An ideal route for lovers of nature and history, discovering a lesser-known Normandy shaped by legends, landscapes and centuries of stories.
