Cross the Bay of the Somme from Crotoy, take the steam train back and then go to Le Hourdel to see the seals, that's all you need for a wonderful holiday. https://youtu.be/nenNw-_0ADE

The dike at Favières is a hiking trail that takes you to the edge of the Bay of Somme, a nature reserve that is home to a rich biodiversity of fauna and flora. It was built in the 19th century to protect the land from the sea. The sea wall offers a panoramic view of the bay, where you can observe the changing colors of the water, the sandbanks and the marshes. You will also be able to spot many birds, such as herons, egrets, ducks and geese.

At Cape Hornu you can enjoy a panoramic view of the bay and its wildlife. You can follow the path along the coast, passing by the Chapelle des Marins, a small chapel dedicated to sailors who lost their lives at sea. You will also discover the charming town of Saint-Valery-sur-Somme, with this medieval street plan, its ancient ramparts and its colorful houses. It's a great way to experience the beauty and history of this area.

Cap Hornu is a cape located near Saint-Valery-sur-Somme, on the south bank of the Bay of Somme. The name Cap Hornu comes from the Picard word “hornu”, which means “horned” or “pointed”, and refers to the shape of the cape. The cape was also known as Cap Saint-Valery in the past. The history of Cap Hornu is closely linked to that of Saint-Valery-sur-Somme, which was a strategic port and a medieval town that witnessed many historical events. In 1066, William the Conqueror departed from Saint-Valery-sur-Somme with his fleet to invade England. In 1431, Joan of Arc was imprisoned in Saint-Valery-sur-Somme before being transferred to Rouen. In 1568, a massacre of Huguenots took place in Saint-Valery-sur-Somme after a battle between Catholics and Protestants

The Bay of the Somme or Somme Bay (French: Baie de Somme) is a nature reserve in the Somme department in northern France. This bay has an area of 70 km² and extends from Le Hourdel to Saint-Quentin-en-Tourmont. The bay is formed by the estuary of the Somme, which flows into the Channel here. A smaller river, the Maye, also flows into the bay here. The bay consists of mud flats and salt marshes, and the fresh water is carried north by the Fleuve marin côtier, a coastal current along the Picardy estuaries. The bay is rich in life forms, both marine animals, water birds, seals and the like. Sea lavender, sea wort and samphire are some of the characteristic plants on the salt marshes. The bay is also important from a cultural history point of view. For example, William the Conqueror set out from Saint-Valery-sur-Somme to conquer England. https://nl.wikipedia.org/wiki/Baai_van_de_Somme
