If you're planning a plan for the last weekend of August in Seine-et-Marne, here’s the run-down of the department’s flea markets and car boot sales. This Saturday the 29th and Sunday the 30th of August 2026, around a dozen communes in 77 are hosting events for bargain-hunters ahead of the new school year. Between village flea markets, summer car boot sales, and a few artisan markets, the lineup offers plenty of chances to go treasure-hunting.
The Saturday, August 29 kicks off quietly with just one major event on the agenda. In Guérard, a flea market takes over Montbrieux, an occasion that draws bargain hunters and curious locals to a pleasant rural setting. A clothes swap is also organized in Bagneaux-sur-Loing at 43 Rue du Gâtinais, perfect for snapping up affordable fashion pieces before the new season.
The dimanche 30 août is shaping up to be much livelier with about ten events spread across the department. The day’s main gathering takes place in Saint-Barthélemy for the Saint-Barthélemy festival flea market, on the communal field opposite 21 Rue du Puits, a traditional event that combines village festivity with a spot of thrifting. In Bassevelle, the annual flea market unfolds on Rue de la Mairie, a must-attend for local enthusiasts.
Mons-en-Montois is hosting a combined flea market and artisanal market on the village square, Rue de la Croix Rouge—an excellent chance to mix rummaging for bargains with discoveries from local craftspeople. Over in Voinsles, the flea market is held at the stadium, while Villiers-sous-Grez is also staging its August flea market at the stadium, two sporty and convivial events.
Château-Landon hosts its flea market in the parking lot, a convenient and well-located gathering. Couilly-Pont-aux-Dames is holding its flea market at 30 Avenue Constant Coquelin, while Darvault runs its event at the town’s community hall. Doué is organizing a flea market on the parking lot by the community hall and at the playground, a pleasant setting for a family outing.
Saint-Méry rounds out the lineup with its garage sale on the road to Mormant, a rural gathering beloved by locals in the area. These village events often preserve a friendly, authentic atmosphere, far from the hustle and bustle of large urban showcases. They offer a great chance to discover the charm of rural Seine-et-Marne while snagging some bargains.
This weekend, August 29–30, signals the close of summer and the dusting off for the new season. The department stays busy on the bargain-hunting front, with major events like the flea market in Dammarie-les-Lys, held four times a year with around 800 exhibitors, and the Torcy flea market in October, welcoming more than 500 vendors. The city of Meaux also runs its monthly flea market at the fairgrounds, a must for regulars.
For this particular weekend, opportunities are varied and well spread across the department. Fans of traditional flea markets will head to Guérard, Saint-Barthélemy and Bassevelle, while those who prefer village-wide yard sales will enjoy Voinsles, Villiers-sous-Grez, or Château-Landon. The Mons-en-Montois artisanal market offers a fine alternative to discover local craftsmanship. September's return to normal activity also looks busy, with numerous events already scheduled, notably in Beaumont-du-Gâtinais and La Ferté-sous-Jouarre starting September 5.
In short, this weekend of August 29–30, 2026 in Seine-et-Marne offers a lively lineup for every bargain hunter ahead of the new season.
