A change of pace for the flea markets and rummage sales in the Essonne (91) this weekend of September 26-27, 2026. After a fairly tame slate last week, the department is lining up around fifteen sales. Headlining is the Brocante du Bout Galeux in Palaiseau with more than 500 exhibitors expected.
Across our forays into Essonne’s flea markets, one takeaway stands out: the last weekend of September is often among the busiest of the season. Attics are emptied before winter, and vendors squeeze in the final pleasant days. Saturday stays quiet, but Sunday the calendar fills up, like a suitcase on the return from vacation.
No suspense: it’s the Bout Galeux Flea Market that will set the pace this Saturday and Sunday. Organized by the Bout Galeux merchants’ association in partnership with the City of Palaiseau, the event has been running for nearly five decades. Stalls line Paris Street, the main artery of the town center.
This year again, the Palaiseau flea market shares the spotlight with the Festival Montagne & Musique, which is marking its 29th edition. In the morning we hunt for bargains, in the afternoon we watch an international lumberjack competition, and we wrap up with a free concert, featuring Louis Bertignac on Sunday evening. All the details can be found in our article about the Festival Montagne & Musique à Palaiseau.
In the northern part of the department, Sunday unfolds along the RER B line. After Palaiseau, Bures-sur-Yvette hosts its big flea market in the town center, just a few stops away. On the Massy side, the Atlantis district flea market brings Rue Ampère to life, while Morangis celebrates Saint-Michel just a stone's throw from Orly Airport.
Further east, Mennecy is rolling out its autumn flea market along Avenue Darblay, while Villabé and Ballancourt-sur-Essonne are betting on more local formats. Sainte-Geneviève-des-Bois completes the picture for those staying along the Orge.
Shopper enthusiasts head southward. Boutervilliers, near Étampes, and Prunay-sur-Essonne, where the vide-grenier spills into the village fête, offer a more rustic, countryside vibe. In La Ferté-Alais, the "front-yard" format turns sidewalks into one-day storefronts, a pleasant way to stroll from house to house. Champcueil brings up the rear, on rue du Vivier.
Parents would do well to mark Breuillet on their calendars. The town kicks off a clothing fair on Friday and Saturday, followed by a Kid's flea market on Sunday—perfect for refreshing toys and kids’ clothes before winter. In Morsang-sur-Orge, the Red Cross braderie offers great bargains while supporting a good cause.
This program speaks to both regular bargain-hunters, who will head to Palaiseau as soon as it opens, and families looking for a free outing to close September. We like the blend of the big urban flea market with the smaller village yard sales, which lend themselves to a relaxed stroll.
Practically speaking, admission to all of these events is free. Schedules vary by town and can change, so a quick check of the town halls’ calendars before you head out is wise. In Palaiseau, you’ll want to take the RER B, as parking is likely to be tight with the flea market and the festival both on. Don’t forget cash and keep an eye on the forecast—the rain could thin out the stalls.
