Set in the green surroundings of the cour de la Ferme de Boussy-Saint-Antoine, in Essonne (91), the Fête de la Nature 2026 runs from May 12 to 25. This biennial, free and open-to-all event offers four days of discovery focused on local flora, fauna and natural heritage, with activities for both kids and adults.
The festivities kick off on Thursday, May 21 with the exhibitions on view from 10 a.m. to 12 p.m. and from 2 p.m. to 6 p.m. under the glass roof of the Gérard-Philipe Hall and in the Jacques-Chamaillard room. On the menu: boxwood sculptures by François Pernette, land art created by children from ALSH with the Imagiers du Val d'Yerres, and photos devoted to birds. A lovely, calm, contemplative start, before a Friday evening that promises to be much livelier.
Meet us next on Friday, May 22. From 7 p.m., amateur photographer and ornithologist Bruno Mathieu will take the floor in the Salle Gérard-Philipe to share his birdwatching trips in the Yerres valley. An accessible talk, perfect for anyone curious about ornithology without needing to be an expert. François Pernette will then follow with a guided tour of his sculptures carved from centenarian boxwood, a noble, rare material that gives the exhibition a notably distinctive edge.
The highlight of the evening is the eco-concert Rock Return Band, slated for 8 p.m., with an entry that’s anything but ordinary: no ticket, but 10 caps per person (or 25 for a family). These caps are then handed over to the association Un bouchon, une espérance for recycling and a charitable sale. Bring a blanket or a sheet to picnic in the courtyard, with three food trucks on site for the occasion. During the intermission, a playful air-guitar contest led by the young members of the enfants city council promises a few good laughs.
The Saturday, May 23 is shaping up as a family-friendly day. The program kicks off at 10:30 with a aromatic plants repotting workshop organized by the association Boussy Nature at the Jardin des colibris on Avenue Charles de Gaulle. At noon, head to the Ferme courtyard for a big picnic, followed by a cooperative outdoor game from 2 to 5 pm. Late in the afternoon, local historian Marc Desenne will frame his talk around "20 Fantastic Women in the Yerres Valley," a subject that artfully blends history with the region.
Sunday 24 May is dedicated to nature walks: a session on the theme "Trees and Climate Change" with Nicolas Bigot of SyAGE starts from the Cour de la Ferme at 10 a.m., followed by a flora walk with Boussy Nature at 2:30 p.m. Free activities, accessible without registration, with just sturdy footwear required.
The week wraps up on Monday, May 25 with a more reflective note, as the Calmattitude association offers a 6 p.m. sophrology session followed by an art mediation workshop at 7:30 p.m., both in Salle Noureev. For these two sessions, registration by email is required at calmattitude91@gmail.com.
This event appeals to both families with children and nature-minded visitors, to wildlife photography enthusiasts, or to fans of local history. Admission is free for all activities, with the exception of the concert on May 22, when you’ll need to bring your own earplugs. All activities take place in the courtyard of the Farm of Boussy-Saint-Antoine, just minutes from Montgeron and Brunoy. The full program is available on the official website of the town of Boussy-Saint-Antoine.
