To the south of Baie lies Pointe du Hourdel with its lighthouse and pebbles. On the opposite shore, the Marquenterre Ornithological Park forms the centre of the Baie de Somme Nature Reserve. Several trails allow you to discreetly observe migratory birds in their natural environment. Grab a pair of binoculars and discover their way of life. In the spring, the grey herons and white storks make their nests here, while the small islands and meadows contain avocets, oystercatchers and crested lapwings. Even the rare black stork can be seen at times. These protected natural environments are also home to numerous mammals.
Switch from the bird to the horse and discover the surrounding area astride the Henson, the breed from Baie. Other surprises you may find on your journeys include the herds of salt meadow sheep that graze in the mollières and, in particular, the seals. These virtually died out during the 1950s, but today, thanks to protective measures, a colony has set up home in Baie. They can be observed from the coast with a pair of binoculars or a telescope. Observation sites are located along the ‘white route’ between Le Hourdel and Cayeux-sur-Mer. They can also sometimes be seen from the Saint-Valéry sur Somme quay.
