The great autumn flea market in the legendary racecourse setting
For more than thirty-five years, Soisy-sous-Montmorency has invited brocante enthusiasts and families to its annual flea market, set up on the vast green spaces of the Enghien-Soisy Racecourse, Place André Foulon. This exceptional site, one of the finest racecourses in Île-de-France, provides an ideal outdoor setting for a day of bargain hunting.
The event brings together more than 200 exhibitors each year, offering a wide variety of items: books, furniture, toys, crockery, clothing, trinkets, vinyl records, old tools and all manner of objects. Private sellers and professional dealers mingle in a warm atmosphere, delighting collectors and families alike.
Beyond the market itself, the brocante is a popular celebration that fills Soisy-sous-Montmorency from the early morning hours. Children are not forgotten: free inflatables are reserved for them. Catering is provided on site by the association Portugais Unis Avec Tous de la Vallée de Montmorency, ensuring a convivial atmosphere from 8 AM to 6 PM.
