This loop between nature and heritage will introduce you to 2/3 of the 39; going against the flow of 36 and 37, you will arrive at Jars and its vast 7 hectare body of water; then the route will let you discover the many traditional rural houses still hidden in the bocage – the entire return will be through the woods and forests (Nancray, Ivoy) before arriving at the superb Château de la Verrerie, an essential passage on the Jacques Cœur road . It's not a "pure mountain bike" route, quite rolling and not technical.
