This WHS is a vast valley dotted with castles, forts, chateauxs, cathedrals, vineyards and good food. Perhaps the most visited is Chambord with the double helix stairway. I visited Amboise, Blois, Chenonceau, Azay le rideau, villandry, chaumont sur Loire. The entrance fees are quite expensive but I would suggest visiting different chateaux and not only Chambord, not only to avoid the crowds but also to better grasp the cultural value of this WHS.
