Yvelines flea markets and garage sales on June 27–28, 2026

Flea markets and garage sales in the Yvelines are gaining traction this weekend, June 27–28, 2026, with around ten events—from Le Vésinet to Marly-le-Roi, via Bougival and Buchelay. Here’s where to hunt for bargains.

After a weekend of June 21 that was a little slow, swept up by the Fête de la Musique, the program of flea markets and yard sales in the Yvelines (78) is rising again for this last Sunday of June. About ten venues are on the lineup, led by the big vide-grenier in Vésinet centre, the brocante du Vieux Marly, and the vide-grenier de la Saint-Jean in Bougival, not forgetting the Mantois area and the southern part of the department. We’ve compiled the schedule by day to help you pick the right rendezvous based on your corner. Find also our selection of flea markets and yard sales in Île-de-France.

Practical note: admission is free everywhere. The hours vary from town to town, and most of these events start early in the morning. For details, contact the towns or the organizing associations directly. In this late-June period following a heat wave, be sure to check whether outdoor happenings are still on and what the day's weather will be: a hat, a reusable bottle, and sunscreen are essentials for a relaxed bargain hunt. For temperatures, rely on Météo-France.

These outings appeal to every type of shopper. The treasure-hunters will hit the Vésinet centre flea market, our weekend favorite for its city-and-park vibe and shaded streets, or the Old Marly antiques market, ideal for pairing vintage finds with a stroll near the royal domain. Seine-side fans will enjoy Bougival and its Saint-Jean festivities, Rolleboise, and Mézières-sur-Seine. And to stay in urban mode, Poissy on Saturday and Montigny-le-Bretonneux on Sunday are easy drives from Paris.
