Fête Nature – Cergy Oise Valley

The department of Val-d’Oise hosts a series of biodiversity workshops and nature walks across its major urban parks in the Cergy area. Deeply anchored in these green spaces were developed to provide essential breathing room for the administrative and industrial heart of the metropolitan area. The event highlights the modern identity of the department as a leader in urban ecology and social inclusion through environmental education. Visitors can participate in bird-watching sessions and workshops on identifying rare urban flora with regional expert naturalists and associations. This initiative has a significant social impact by connecting the local youth with the environmental challenges of their own territory. For urban planners it provides valuable data on how regional parks support both social cohesion and ecological resilience in dense areas. The festival ensures the legacy of the department’s green lungs is valued and protected by its residents for future decades.
