The Yvelines (78) kick off autumn without dragging their feet. For this weekend of September 26-27, 2026, we've kept from our trips in the 78 a handful of stops that are worth the ride. On Île des Impressionnistes, the Foire de Chatou sets up its lanes of flea-market stalls and antique dealers, right beside the Maison Fournaise where Renoir painted his Luncheon of the Boating Party. And for neighborhood yard-salE-style discoveries, our selection of the flea markets and garage sales of the Yvelines features around twenty addresses, from Poissy to Septeuil.
In Saint-Germain-en-Laye, the birthplace of Claude Debussy, the Saint-Germain en Live festival is entering its final two days, with Ladaniva on Saturday and Jérémy Frérot closing on Sunday. The best part is outside too: free performances will enliven Place du Marché-Neuf and the city center streets all weekend (program on the city's website).
Before you head out, take a look at the weekend forecast and our update on the transport disruptions from September 21 to 27, 2026, as several RER and Transilien lines in the 78 are affected by work. To extend the escape, our guide what to do in the Yvelines gathers addresses to explore all year round.
