Welcome to Baie de Somme
Famed for its galloping tides and the seals that lounge on the Pointe du Hourdel sandbanks, this sparkling estuary – the largest in northern France, at 72 sq km – affords delightful, watery views as the cycle of the tides exposes and conceals vast expanses of marshland and sand. The area's wetlands provide hugely important habitats for hundreds of bird species. You can explore the bay by boat, kayak, outrigger canoe and – at low tide with a guide – on foot.
Both Le Crotoy, on the northern bank, and St-Valery-sur-Somme, on the south side, make excellent bases for exploring the area.
