The Fête d'Osny: a commune celebrating

The Fête d'Osny is the unmissable festive event for the inhabitants of Osny, a residential commune in the Cergy-Pontoise agglomeration located a few kilometers from Pontoise, the prefecture of Val-d'Oise. Every summer, the town transforms into a festive space to host a popular and family-friendly festival that brings together the entire local community.

The Town of Osny and its local associations invest each year to offer a rich and varied program, suitable for all audiences. Concerts by local and regional bands, fairground attractions, games and workshops for children, catering, and associative stands make up the program of this friendly summer festival.

Music and entertainment

The Fête d'Osny offers an eclectic musical program that reflects the diverse tastes of the commune's inhabitants. Rock, French variety, world music, and jazz bands take turns on stage to liven up the festive evenings and afternoons. Popular dances perpetuate a dancing tradition highly appreciated by the older generation.

A participatory event

The involvement of local associations is at the heart of the Fête d'Osny. Sports clubs, cultural associations, and leisure groups actively participate in the organization and animation of the festival, running stands, organizing demonstrations, and contributing to the friendly and festive atmosphere. The festival is thus a reflection of the richness of Osny's associative fabric.

Osny, a commune between Pontoise and nature

Osny benefits from a pleasant living environment between the urban center of Pontoise and the surrounding natural spaces. The commune is crossed by the Viosne, a tributary of the Oise, and has significant green spaces. This natural setting contributes to the relaxed and pleasant atmosphere of the annual festival.
