The village of Marnay-sur-Seine has 230 inhabitants and is located between the banks of the river Seine and the old transport canal that barges once used to transport wheat and wood to Paris. Conveniently nestled at the cross roads of the Champagne region, the Parisian region of Ile de France, and Burgundy, participants to camac programmes can benefit from the French countryside without being cut off the cosmopolitan richness of Paris.
