Bois de Cise
Highlight • Forest
This coastal wood was originally a wild wood which became a place for hunting with hounds. Bois de Cise was then sold in the form of lots, by a visionary who would stop at no means.
Today, it is a charming vacation spot and stroll, best discovered on foot along the small paths and wooden stairs that line the site. Very pretty villas bear witness to the prosperous years before the First World War.
Like Victor Hugo in his time, don't forget to go to the panorama. Fantastic viewpoint where you can see the Baie de Somme estuary.

Bois de Cise
Highlight • Other
The Bois de Cise is an exceptional natural area, a small natural forest, originally wild and abandoned, which became a famous seaside resort during the Belle Époque under the leadership of a visionary who stopped at nothing.
This coastal forest was originally a wild forest and a hunting ground in the Middle Ages. At the end of the 19th century, the Bois de Cise was sold off in lots on the initiative of a property developer and became a famous seaside resort of the Belle Époque.
Today, it is a charming holiday and walking area that is best explored on foot via the narrow paths and wooden steps that crisscross the area. Very beautiful villas bear witness to the prosperous years before the First World War.
Don't forget to go to the panorama, like Victor Hugo in his time, a fantastic viewpoint from which you can see the mouth of the Bay of Somme.
