The Fête de la Nature 2026 is coming to Seine-Saint-Denis too!

This 20th edition of the Fête de la Nature is a chance to (re)discover our environment and to highlight why protecting it matters, all free and outdoors.
In Seine-Saint-Denis (93), kids and grown-up curiosities alike, groups of friends and families will be able to take part in creative workshops, go on short family-friendly hikes, dip a toe into botanical photography via cyanotype, observe the insects at Parc du Sausset, or journey back in time at the Archéosite de la Haute-Île in Neuilly-sur-Marne. Several venues are taking part in this national event: community gardens, departmental parks, urban farms, and natural sites are mobilizing to offer a series of sessions—often by reservation—with limited capacity. So be sure to book the activities you’re most excited about as soon as you can!
