Seine-et-Marne kicks off October with a busy weekend, offering a mix of castles and museums free on Sundays, the Science Festival, the Torcy Swap and Flea Market, and Disneyland Paris pumpkins, on October 3–4, 2026.
The 77 kicks off autumn at full speed: this weekend of October 3-4, 2026, we’re off flea-market hunting in Torcy, celebrating science with the family, and taking advantage of free-entry to castles on the first Sunday of the month.
The Seine-et-Marne department (77) opens autumn with a lineup that invites you to get out. For this weekend of October 3-4, 2026, we've gathered ideas spotted during our visits across the department, from Fontainebleau to Marne-la-Vallée, via Torcy and Moissy-Cramayel.
This Sunday, October 4, falls on the first Sunday of the month, and several châteaux et musées de Seine-et-Marne will offer free admission. In Fontainebleau, the exhibition Le panache des Lumières traces how the figure of Henry IV regained prominence under Louis XVI. It remains on display until January 25, 2027.
The Fête de la Science also kicks off Friday, October 2, and runs through October 12, 2026. In Seine-et-Marne (department 77), free activities are multiplying, including at La Rotonde, the Moissy-Cramayel-based media-ludothèque, where 6-11-year-olds can step into the shoes of archaeologists on Saturdays (booking required).
For bargain hunters, the 45th Torcy Flea Market is stealing the show, with around twenty pop-up sales from Meaux to Seine-Port. And for those who like a family-friendly scare, the Disneyland Paris Halloween Festival is in full swing until November 1.
