Caesar's Camp is an earthen mound that is over 2000 years old. The site dates back a few centuries before the Roman period. The more appropriate name for this historic site is “City of Limes”. It is in fact a “Gallic oppidum” or more certainly Gallo-Belgian which dates from well before Julius Caesar! This mound is a very long fortification which protected an area of more than 50 hectares. This earthen rampart is 3600 meters long. It still measures 9 to 12 meters high today depending on the location. The mound is framed by an exterior and interior ditch, which made it almost impassable. You are thus progressing on a historic path, an “antique route” which dates from Antiquity.

This coastal wood of approximately 60 hectares is classified as a Sensitive Natural Area by the Department of Seine-Maritime, which offers hikes there all summer. You will discover a diversity of forest species (beech, oak, maple, cherry, chestnut, etc.), a wealth of ferns characteristic of humid undergrowth. Thanks to its soft humus, we very frequently observe a remarkable multi-colored carpet. In spring, we find primroses, daffodils, bluebells and violets in the undergrowth. In the fall you can see a carpet of blueberries.

It is a dead end to see the coast which is certainly worth the detour. In the hollow of the valley, at the end of a quiet path that winds through the forest, ending in a crucible in the cliff, this small beach awaits you. The ascent is done on percentages of about 5%, so it is not so difficult, on the scale of the firecrackers that crisscross the region.
