Audio Guide Baie de Somme
app, one-time €4.99
The Baie de Somme is a vast 190-square-kilometre estuary in northern France where tidal mudflats, sweeping dunes, and medieval harbour towns converge in one compact region. France's largest mainland harbour seal colony hauls out on the sandbanks here, and William the Conqueror assembled his invasion fleet in this same bay in 1066. Whether you follow the narrow streets of a fishermen's quarter or ride a steam train along the estuary's edge, the bay rewards slow, attentive travel.

01
The Bay of Somme
William the Conqueror sheltered his invasion fleet here in 1066 while waiting for favourable winds, and today the same 190-square-kilometre estuary hosts over 300 bird species and France's largest harbour seal colony on the mainland. It is a Ramsar and Natura 2000 protected site shaped by rising seas after the last glacial period.

02
Saint-Valery-sur-Somme
Founded around 615 when Saint Valery established an abbey at the Somme estuary, this medieval town became a pilgrimage centre supported by Kings Clotaire II and Dagobert I. Its medieval ramparts, colourful fishermen's quarter, and direct connection to the Norman Conquest make it one of the most historically layered towns on the Picardy coast.
-
03
The Seals of the Bay of Somme (Pointe du Hourdel)
Harbour seals were hunted to near-disappearance here in the 20th century, but after protections introduced in the 1970s the colony reformed on its own, with births recorded every summer since 1992. Today Pointe du Hourdel hosts the largest harbour seal colony in metropolitan France, visible from the shore at low tide.

04
Marquenterre Park
This 200-hectare ornithological reserve began as a tulip and hyacinth polder after World War II; when Dutch competition made flower-growing unprofitable, owner Michel Jeanson converted it into a bird sanctuary in 1973. It now records over 317 bird species and sits at the northern edge of the Baie de Somme, making it a key stopover on Atlantic migratory routes.
-
05
Guillaume Gate
Joan of Arc passed through this 11th-century gate on 20 December 1430, on her way to Rouen and her trial. Named after William the Conqueror, whose fleet sheltered in the bay in 1066, it stands with its two round towers and Gothic arch as one of the oldest surviving city gates in Saint-Valery-sur-Somme, classified as a Historic Monument since 1907.
-
06
The Somme Bay Railway
Opened in 1858 to serve the port of Saint-Valery and initially hauled by horses, this metre-gauge line played a logistical role in World War I before reinventing itself as a heritage steam railway. It still runs along the estuary between Noyelles-sur-Mer, Saint-Valery, and Le Crotoy on the original tracks.
-
07
Le Courtgain (sailors' district)
The name 'Courtgain' comes from a local dialect phrase meaning 'small wage,' a wry nod to the modest earnings of the shrimp fishermen who lived here in the 18th and 19th centuries. The district's narrow downhill streets and colourful brick-and-daub houses survive largely intact below Saint-Valery's medieval walls, and Guy de Maupassant is among the writers linked to its story.
