It is located between the Bresle and Yères valleys.

Covering more than 9,000 hectares (22,239 acres), this forest is planted with 70% of beech trees, 20% of oak trees and the remaining 10% consists of hazelnut trees, maple trees, sycamore trees... Divided in three parts: the Triage, the Haute-forêt d'Eu (upper part) and the Basse forêt d'Eu (lower part), this forest has been occupied by men even before the Roman occupation. This forest has belonged to the House of Orleans for a long time, but has been owned by the state and the Département of Seine-Maritime since 1915, hence the name of joint property ownership.

There are interesting and unusual things to see: the signposts, usually made of wood, are here made of cast iron and bear the name of important personalities from the town. The forest is home to a wealth of flora and fauna. Besides the sedentary animals, many bird species stop there to rest since the forest is located along an important north-south migration corridor. The "Quesne à leu" (wolves' oak tree) makes for a pleasant walk. It has unfortunately fallen one night in June. The tree's girth of more than 4 metres (13 ft.) made it the patriarch of the forest. It is traditionally said that the last wolf in the forest was killed at its feet. A nice walk in the heart of one of the most beautiful beech groves in France to add to your schedule.
