About Guernes Flea Market

Every year in June, Guernes holds its summer flea market on the rue de Mantes. Organized by the town hall and local associations, this annual event gathers about fifty exhibitors and welcomes bargain hunters from across the Yvelines for a friendly outdoor day, with on-site catering. An authentic event in a preserved village of the Seine valley.

Guernes summer flea market: a village tradition

Guernes is a small rural commune of about 1,000 inhabitants located in the Seine valley, a few kilometers from Mantes-la-Jolie. Every year in June, the village comes alive to host its summer flea market on the rue de Mantes, the main street that crosses the locality.

About fifty exhibitors in the heart of the village

With around 50 exhibitors, the Guernes flea market remains a village event, modest in size but full of charm. Stalls line rue de Mantes, turning this normally quiet street into a lively bargain-hunting lane.

On-site catering and friendly atmosphere

As often in village flea markets, organizing associations offer on-site catering: cold drinks, sandwiches, fries, crepes, sometimes homemade pastries prepared by volunteers.

Guernes, a Seine valley village

Guernes belongs to the string of villages along the Seine in the Mantes area, between Moisson, Rosny-sur-Seine, and Rolleboise.

A tip for savvy bargain hunters

Flea markets like Guernes, small and held in lesser-known villages, are often great spots for savvy bargain hunters. Competition is lower than in Paris or larger cities.
