There's no regularly scheduled Proust tour, but you can do it yourself or get in touch with a guide. From 2 to 4 p.m. on Thursday, a guide is available to describe Proust's life while he resided there.
Admission is free.
Then you'll need to rent a car for a two-day trip to Normandy. The first stop would be 16 miles southeast of Chartres in Illiers Combray, called Combray in Proust's novels. Madeleines are served at breakfast, naturally. The bedroom has been decorated exactly as Proust described it, with heavy red and mauve curtains and a big brass bed. The view of the sea is spectacular.
