Flea markets and garage sales in Yvelines, September 5–6, 2026 - 78

After a rather quiet summer, the program of flea markets and yard sales clearly expands again in the Yvelines (78) for this first weekend of September 2026. Saturday kicks off the lineup with a single event, but Sunday unfolds no fewer than ten addresses across the department, led by the big Foire aux greniers in La Queue-les-Yvelines and the indispensable flea market in Tremblay-sur-Mauldre.

A refreshment bar, food, and entertainment by the Knights of Dame d'Anet are on the program, with free admission for visitors.

In Tremblay-sur-Mauldre, the flea market on Rue du Puits d'hiver is a highlight too: a staple for more than twenty years, it attracts over 7,000 visitors each year, with a bar, snacks, pastries and activities for all ages.

The rest of the program nicely rounds out the season kickoff: Goupillières is staging its 33rd edition of the flea market from 6 a.m., while La Celle-Saint-Cloud is banking on a village-fair vibe for its town flea market, with nearly 150 exhibitors—just a few kilometers from Paris.

Practically speaking, admission to all of these events is free. It’s worth checking the weekend forecast on Météo-France before you head out, since the season’s kickoff can bring a few weather changes.

Something to satisfy every bargain-hunter this autumn: fans of big gatherings will head to La Queue-les-Yvelines or Tremblay-sur-Mauldre, while those who prefer village vibes will swing toward Saint-Forget or Tertre-Saint-Denis.
