From the Porte de Montreuil flea market to the Milly-la-Forêt antiques fair, our pick of flea markets and antique fairs in Île-de-France for August 8-9, 2026.
This weekend of August 8-9, 2026, Île-de-France doesn't take a single morning off from treasure hunting: flea markets, antique fairs and car boot sales pop up everywhere from the 12th arrondissement to a 15th-century covered hall in the Essonne countryside. Between the professional flea markets that run every weekend in Paris and the monthly rendezvous further out, the hard part isn't finding a stall to browse — it's choosing which one. Our pick of the weekend is the antique fair in Milly-la-Forêt, held under a medieval hall at the edge of the Fontainebleau forest. What's on your list this weekend?
Porte de Montreuil: Paris's other flea market
A Parisian institution since the 19th century, the Porte de Montreuil flea market gathers around 300 vendors every Saturday, Sunday and even Monday along Avenue du Professeur-André-Lemierre, on the eastern edge of the 20th arrondissement. Less touristy than Saint-Ouen, it's the go-to spot for cheap vintage clothing, bric-a-brac and second-hand tools.
Aligre: the flea market that barely ever closes
Unlike most Île-de-France rendezvous, which run monthly or weekly, the Place d'Aligre flea market runs Tuesday through Sunday — so it's open both August 8 and 9, same as any other week. Tucked beside the covered Beauvau market in the 12th arrondissement, it has traded since 1779: mismatched china, old books, vintage clothes and small objects with more character than value.
Georges-Brassens: a book lover's flea market
Under the old horse-market hall of Parc Georges-Brassens, in the 15th arrondissement, around sixty professional booksellers set up shop every Saturday and Sunday with rare editions, old papers and second-hand books. The 19th-century ironwork hall is worth the trip on its own — it's one of the last markets of its kind still active inside Paris. Details on the Georges-Brassens book market.
Rambouillet: 55 antique dealers on August 9
On the second Sunday of the month, Place Billard in Rambouillet hosts the Rambouillet Bargain Hunters' Rendezvous: 55 professional antique dealers from across Île-de-France set up in the historic town centre. The selection runs tighter than a general flea market, with period furniture and collectible pieces taking the lead.
Montlhéry: a twice-monthly gathering
The Montlhéry flea market runs twice a month, on the second and fourth Saturdays — meaning August 8 is on the calendar. Held on Boulevard du Téméraire in a town best known for its medieval tower and historic racetrack, it's a general-purpose flea market with a loyal, mostly local crowd.
Milly-la-Forêt: an antiques fair under a 15th-century hall
On the second Sunday of the month, around thirty professional dealers set up under Milly-la-Forêt's medieval covered hall, a listed historic monument at the edge of the Fontainebleau forest, for the Milly-la-Forêt antiques fair. Period furniture, silverware and paintings: the selection stays tightly curated, worlds away from the open-field car boot sales nearby.
Étampes: a big flea market surrounded by greenery
On the second Sunday of the month, the Île de Loisirs d'Étampes flea market brings together 100 to 200 vendors — both private sellers and professionals — on its car park, in a leisure-park setting that stands apart from the usual town-centre stalls. Free entry for visitors, one of the busiest flea markets in the southern Essonne.
Bobigny: a solidarity-driven flea market
Every Saturday morning, the Amelior weekly flea market opens at 45 rue de Paris in Bobigny. Run by a resource centre that campaigns for the recognition of informal waste-pickers and the second-hand solidarity economy, it gathers up to 150 vendors — a more committed format than your average car boot sale, reachable by metro.
Arpajon: a car boot sale under 19th-century market halls
On the second Sunday of the month, 50 to 80 private sellers set up in the centre of Arpajon, next to the 19th-century market halls and the Saint-Clément collegiate church. Reachable by RER C, it's a mid-sized car boot sale suited to a shorter outing.
Goussainville: between old village and car boot sale
On the second Sunday of the month, Goussainville holds its monthly car boot sale, a fixture for locals and bargain hunters from the area. The town's preserved old quarter, the Vieux Pays, gives it a different feel from the surrounding suburbs — a modest, regular gathering rather than a big weekend destination.
Also worth knowing: a weekday option
If the weekend isn't enough, the Saint-Mandé Collectors' Market runs every Wednesday morning on Avenue de Paris and Place Gallieni. Île-de-France's largest permanent collectors' market, active since 1989, gathers around forty specialist dealers in old paper ephemera, records, stamps, coins and vintage toys — part flea market, part specialist fair.
Where to go this weekend
From the city flea markets of Paris to the professional antique fairs further out and Bobigny's solidarity-driven car boot sale, Île-de-France has enough going on to fill both days without repeating itself. Find more events across France on our weekend agenda.
