St Firmin is a kitesurf spot on the southern shore of the Baie de Somme (Somme), near Quend-Plage. This section of coast between the Somme estuary and the Picardy shoreline offers a large flat beach with consistent westerly winds.

Best winds from South-West to West and North-West. Very large tidal range — the Somme bay can nearly empty at low tide. Check tides before heading out. A scenic natural spot on the Picardy coast.
