Les Yvelines (78) are spending the final weekend of the All Saints’ school holidays in the Halloween spirit. For the weekend of October 31 and November 1, 2026, we’ve picked out ten things to do that we discovered on our outings around the department, from the forests of Rambouillet to the banks of the Seine.
On Saturday, it’s all about pumpkins and costumes. Children want a good scare, while older visitors sometimes prefer a mystery to solve by flashlight or a walk as night falls early. All Saints’ Day, November 1, falls on a Sunday this year: a day to slow down with an exhibition, a park changing color or a good lunch before classes resume on Monday.
To keep the thrills going, our guide to Halloween 2026 in the Yvelines brings together events planned across the entire 78.
