About Festi'Vallée d'Igny

The Festi'Vallée d'Igny is the town's flagship annual festival, co-organised by the town hall and the entertainment committee. Every September, over 10,000 festival-goers gather for two days of concerts, children's entertainment, an artisan village, a varied food offering, and an evening fireworks display. A popular and friendly event in the beautiful Bièvre valley.

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

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

Two days of celebration 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 prepared by the organisers, is designed to satisfy all generations and desires.

On Saturday, festivities open at 10 AM with the Trifouillette kids, a morning of entertainment specially dedicated to the youngest, then stretch 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 in turn opens with the Trifouillette adulte, a sporty and friendly morning, before continuing with concerts, entertainment, and the artisan village until 6:30 PM. The relaxed atmosphere of Sunday afternoon contrasts pleasantly with the effervescence of Saturday evening.

Concerts: the centrepiece of the program

The musical program of Festi'Vallée is one of the event's great strengths. Each edition offers 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 values of the event. The main stage of Festi'Vallée is a springboard for many artists from Essonne.

The Artisan Village

One of the unique features of Festi'Vallée is its artisan village, which hosts local and regional creators. Jewelers, ceramists, makers of artisanal food products, textile designers: the village stands allow visitors to discover and acquire unique products while supporting local craftsmanship. This ephemeral market is particularly appreciated by residents concerned with responsible consumption and connection with producers.

Catering: a gourmet and diverse offering

The Festi'Vallée offers a particularly comprehensive catering selection. Local associations run stands, providing opportunities to taste various specialties while supporting local community life. Food trucks complement the offering with world cuisine proposals. The conviviality of meals shared with family or friends is one of the essential dimensions of the event.

Igny: a town committed to its festive traditions

The town of Igny, nestled in the Bièvre valley, is a human-sized commune that carefully cultivates its associative fabric and cultural life. The entertainment committee, a historical partner of the town hall, plays a central role in organising the Festi'Vallée and many other events throughout the year. This collaboration between the municipality and the associative world guarantees an event rooted in the realities and aspirations of the population.

Festi'Vallée d'Igny — edition 2026

The Festi'Vallée d'Igny 2026 will take place on Saturday, September 12th and Sunday, September 13th, for two days of celebration. Concerts, Trifouillette, an artisans' village, food stalls, and fireworks are on the program, in the beautiful Bièvre valley.

Festi'Vallée d'Igny 2026
