The Festi'Vallée d'Igny: the great festival of the Yvette valley

The Festi'Vallée is the unmissable annual festival of the town of Igny (91430), a green commune in the Yvette valley in Essonne. Co-organized by the town hall and the municipal animation committee, this event welcomes over 10,000 festival-goers each year over two days, making it one of the most important popular gatherings in the Paris-Saclay area.

Two days of festivities for all audiences

The Festi'Vallée takes place every year in September, marking the end of summer in the most beautiful way. The program, carefully developed by the organizers, is designed to satisfy all generations and all desires.

On Saturday, the festivities open at 10 am with the Trifouillette kids, a morning of activities specially dedicated to the youngest, and then continue until midnight with a dense musical program. The highlight of the evening is a fireworks display that illuminates the valley and brings together spectators of all ages in shared wonder.

Sunday opens with the Trifouillette adult, a morning of sports and conviviality, before continuing with concerts, activities, and the artisan village until 6:30 pm. The relaxed atmosphere of Sunday afternoon contrasts pleasantly with the excitement of Saturday evening.

Concerts: the centerpiece of the program

The musical program of the Festi'Vallée is one of the event's great strengths. Each edition features several concerts covering a wide musical spectrum: rock, French chanson, pop, world music. Local bands perform alongside regional or national artists, in a spirit of discovery and accessibility that reflects the event's values. The main stage of the Festi'Vallée is a springboard for many artists from Essonne.

The Artisan Village

One of the original features of the Festi'Vallée is its artisan village, which hosts local and regional creators. Jewelers, ceramists, food artisans, textile designers: the village stands allow visitors to discover and purchase unique products while supporting local craftsmanship. This ephemeral market is particularly popular with residents who care about responsible consumption and connection with producers.

Catering: a gourmet and diverse offering

The Festi'Vallée offers a particularly complete catering service. Local associations run stands that provide opportunities to taste various specialties while supporting local community life. Food trucks complement the offering with international cuisine options. The conviviality of meals shared with family or friends is one of the essential dimensions of the event.

Igny: a town attached to its festive traditions

The town of Igny, with its 10,000 inhabitants nestled in the Yvette valley, is a human-sized commune that carefully cultivates its associative fabric and cultural life. The animation committee, a historic partner of the town hall, plays a central role in organizing the Festi'Vallée and many other events throughout the year. This public-associative collaboration guarantees an event rooted in the realities and aspirations of the population.
