The brocantes et vide-greniers des Yvelines are stepping up for this weekend of September 26-27, 2026. In the Yvelines (78), the Foire de Chatou spreads its aisles across the Island of the Impressionists, while around twenty towns lay out their stalls—from Poissy to Saint-Arnoult-en-Yvelines on Saturday, and from Bougival to Septeuil on Sunday.
As we wander across the department, one thing has become clear: late September is usually the last big push before the pop-up sales retreat indoors. So let's make the most of it while the lawns and village squares still double as open-air storefronts.
Can't talk about this weekend without kicking off with the Foire de Chatou. For its 111th edition, it brings together more than 300 antique dealers and professional flea-market merchants from all over France. Antique furniture, jewelry, vintage fashion, collectibles: it’s a treasure-hunt stroll through a giant attic nestled between the two arms of the Seine.
Organized twice a year by the SNCAO-GA, the fair relies on the Authenticité-Qualité label and offers a free appraisal service. It’s a reassurance for anyone who's hesitating in front of a Louis-Philippe dresser or a porcelain dinner service. And between two booths, you’re steered toward a quick detour to Maison Fournaise, the place where Renoir painted his famous Luncheon of the Boating Party.
For practical purposes, the fair runs daily from 10:00 AM to 7:00 PM until October 4, 2026, with ticket counters closing at 6:00 PM. Admission is €10 (free for under 15s), and online tickets can help you skip the line. You’ll reach it via RER A, with free shuttles departing from Rueil-Malmaison station. All the details are also available on the City of Chatou’s website.
Saturday, Saint-Arnoult-en-Yvelines takes the spotlight with its 43rd flea-market fair. More than four decades on the books, it's the kind of event that residents in the south of the department circle on their calendars year after year.
To the north, Poissy is pulling double duty with two flea markets on the same day, including the République one. Parents getting their kids' winter wardrobe ready can swing by the Freneuse clothing exchange, a smart way to refresh the wardrobe without breaking the bank.
Sunday sets the tempo as Saint-Michel kicks off the season. The Saint-Michel flea market in Bougival stretches along Quai Clemenceau, with the Seine as its backdrop. A staple event on the last Sunday of September, highlighted by Brocabrac among the month’s must-see happenings in the department. In Feucherolles, the Saint-Michel flea market unfolds in a more bucolic setting, on the edge of the Versailles plain.
For collectors, two destinations stand out. Le Vésinet hosts the 3rd edition of its festival of comics, vinyl and music, a perfect stop to top up a stack of 33‑rpm records or broaden a collection of albums. Villepreux meanwhile stages a general collectibles fair, where postcards, coins and miniatures typically have their place.
Village lovers are spoiled for choice, from Lainville-en-Vexin to Saulx-Marchais, via Toussus-le-Noble and its 14th flea market. More urban, Saint-Germain-en-Laye, Saint-Cyr-l'École and Conflans-Sainte-Honorine with its Broc à brac complete a Sunday that's packed with options. Finally, Neauphle-le-Château hosts a book fair for readers seeking new pages.
This weekend caters to both seasoned bargain hunters, who will head to the Chatou Fair for its antique finds, and families seeking wallet-friendly options at village flea markets. We especially enjoy the balance between big events and more intimate formats, where there’s time to chat with the exhibitors.
A word of advice from regulars: bring cash and a big bag, as many individual sellers don’t accept card payments. It’s also worth checking with the town hall or the organizer before you head out to avoid any nasty surprises. Also take a look at the weekend forecast, since most of these sales are held outdoors.
