3. France's Loire: Chateau Country (2014)

Along the Loire River Valley, the beautiful French countryside is studded with evocative châteaux. Home-basing in Amboise, we visit four unique castles: elegant Chenonceau, massive Chambord, stately Cheverny, and fragrant Villandry. Along the way, we tour Leonardo's home, feed hunting dogs, enjoy the local cuisine, and savor a princely garden.
