As every year, the Fête de la Nature returns in May to invite us to slow down and to cast a new light on the living world that surrounds us. In 2026, the event marks its 20th anniversary and runs from 20 to 25 May across France, and, of course, in the Val-de-Marne (94). Five days of free activities, open to all audiences, to explore the wildlife, the flora and the biodiversity through walks, workshops and encounters with experts and passionate enthusiasts of life.
The need for nature may never have felt more concrete than it does today, and the Festival of Nature has understood this well. This year, living-world themes sit at the heart of the program: we head out to meet the birds, amphibians, insects, and plants that colonize the banks of the Marne, the parcs and the natural spaces of the department. Val-de-Marne has the practical upside of offering, just a stone’s throw from Paris, protected natural habitats of remarkable richness: the Marne’s slopes, the Bois de Vincennes, green corridors... so many playgrounds that are perfect for this week of discovery.
The 2026 program is particularly geared toward the theme of water and biodiversity, featuring several events along the Marne’s riverbanks, focusing on floods and inundations, and the relationships between plants and insects. A wonderful chance to see these landscapes from a different angle—landscapes we often move through without really stopping.

Also remember to reserve your spot for activities that require it.
This event is open to families with kids as well as curious minds of all ages, to nature lovers and to beginners who have never yet paused to watch a butterfly or listen to the frogs of the Marne. No need to be an expert: that’s precisely the spirit of the Nature Festival — welcoming everyone, without pretension, to share in the joy of all living things.
