The great traditional Easter Monday flea market in the Coulée Verte Park
Every Easter Monday, the town of Oinville-sur-Montcient hosts one of the most anticipated flea markets of the Yvelines: Oinville en Fête. For its 31st edition, the Coulée Verte Park welcomes around 180 exhibitors for a great day of bargain hunting in an exceptional green setting. An essential rendezvous for Vexin bargain hunters, this event brings together private exhibitors and professional dealers in a festive and family atmosphere.
Every Easter Monday for more than three decades, the small village of Oinville-sur-Montcient, in the far northwest of the Yvelines, at the gates of the French Vexin, transforms into a huge outdoor flea market. Organized by the Oinville en Fête association with the support of the town hall, this flea market is one of the oldest and largest in the area.
The Coulée Verte Park offers an absolutely ideal setting: a beautiful shaded green space, crossed by the Montcient stream, which can accommodate around 180 exhibitors in excellent conditions.
Private exhibitors and professional dealers share the spaces to offer a very diverse selection: antique furniture, crockery, old linen, toys, trinkets, glassware, books, vinyl, tools, vintage clothing.
Besides the flea market, Oinville en Fête traditionally offers a festive atmosphere with a refreshment stand and small catering.
A rural town of around 800 inhabitants, Oinville-sur-Montcient is part of the French Vexin regional natural park.
The 31st edition of the Oinville en Fête flea market was held on Easter Monday April 6, 2026 in the Coulée Verte Park. 180 private and professional exhibitors animated the park all day. Free admission.
