The territory of the Oise-Pays de France Regional Nature Park covers 70 municipalities in Oise and Val d'Oise.

Filled with history, it is intimately linked to the Pays de France, the land of the Capetians and the favorite place of residence of the Merovingians.

While traversing the vast territory of the PNR, one still notices the royal presence: between abbeys and castles (Abbey of Chaalis, Domaine de Chantilly).

Real "green lung" in the North of the capital thanks to its 3 essential forests (Ermenonville, Halatte, Chantilly) and the many ponds and valleys which constitute it.

The Park enjoys a great diversity of natural environments: from the sandy moors of Ermenonville to the lawns of the limestone hillsides of the Oise, passing through marshes!

The Oise-Pays de France Regional Nature Park is not just a vastly natural place. It also contains countless typical villages with old buildings, reflecting its character!

A vast place for walks, strolls, family outings and daydreams, the PNR is a treasure!
