The weekend of May 16-17, 2026 lines up a real week of bargain hunting in the Yvelines. The département alternates prestigious sites and rural villages. The programme runs from the professional flea market in Rambouillet to the small garage sale in Mittainville, a village of just 370 inhabitants.
The Chevreuse valley and the Mantois area welcome the first proper sunshine of May. The season of village farfouilles peaks now. For lovers of serious pieces? Head to the antique dealers. For those after good deals? Aim for the villages around the Rambouillet forest.
Here is a 7-stop tour, sorted from Saturday May 16 to Sunday May 17, from southern Rambouillet to the northern Mantois area.
Saturday May 16 — the kick-off
Brocante du CSL Bullion — 60th edition, exceptional jubilee
The event of the year in the Chevreuse valley. The Brocante du CSL Bullion celebrates its 60th edition on Saturday May 16, 2026. It is one of the oldest flea markets in the southern Yvelines.
The meeting point is rue des Aulnettes, in the natural Framboisines area. Up to 150 stalls spread out on the wooded lawn. The event is part of the larger Fête de Bullion, which runs over 4 days.
How much does it cost to exhibit? 7 € per linear meter with a 5 meter minimum, 10 € on the day without reservation. Entry is free for visitors. See the page.
Sunday May 17 — the big day
Rendez-vous des Chineurs de Rambouillet — 55 antique dealers on Place Billard
The meeting point for fans of fine pieces. The Rendez-vous des Chineurs de Rambouillet takes place every second Sunday of the month on Place Billard, right in the historic centre. The May 17 date falls on the third Sunday, but the monthly edition stays active for this weekend according to the 2026 calendar.
Why does this market appeal to pros? 55 antique dealers and professional brocanteurs from all over the Île-de-France region set up their stalls near the presidential château. Antique furniture, silverware, paintings, rare books: this is where you hunt the serious piece. See the page.
Foire à tout de Richebourg — 140 stalls in the heart of the Mantois
The heavyweight of the northern département. The Foire à tout de Richebourg brings together about 140 stalls on the meadow behind the village hall. The local festival committee has run the event for years.
The exhibitor rate? 5 € per linear meter with a 2 meter minimum. For visitors, entry is free. The country setting, halfway between Houdan and Mantes-la-Jolie, gives an authentic feel. See the page.
Vide-grenier de Richebourg — the village extension
To pair directly with the Foire à tout. The Richebourg garage sale mobilises village amateurs on the same May 17. Two complementary events in the same rural town in the Yvelines: handy for filling a morning of bargain hunting without moving the car.
Entry is free. You can walk between the two sites. A good option for those who want to extend the Richebourg tour without restarting the engine. See the page.
Brocante du Comité des Fêtes de Mittainville — pure village spirit
Total change of scale. Mittainville counts only 370 inhabitants. The village sits at the far west of the Yvelines, on the edge of Eure-et-Loir. The Comité des Fêtes brocante settles at the Pâtis, on the lawn in front of the Fernand Chaudier village hall.
For lovers of authenticity, this is a textbook case. Entry is free. Stallholders are private only. Snack bar run by volunteers, no fuss vibe. See the page.
Vide-grenier d'Orcemont — bargain hunting at the edge of Rambouillet forest
Another small rural village, this time in the south of the département. The Orcemont garage sale takes over the village centre on May 17. Just a few kilometers from Rambouillet, you are right in the state forest.
The event is family-friendly, on a human scale, with both private and professional stallholders. The atmosphere echoes the village markets of old. For visitors? Free entry. See the page.
Bourse aux vêtements de Septeuil — the deposit-resale format
A different format in the rural Yvelines of the Mantois. The Septeuil clothes exchange works on the deposit-resale principle. Families drop off what they no longer wear, buyers refresh the spring wardrobe at low prices.
The event is held indoors, which sets it apart from the open-air gatherings of the weekend. A solidarity-driven, affordable and eco-friendly vibe. Ideal for those equipping kids and teens before summer. See the page.
