If only the mighty walls of Chateau de la Roche-Guyon could talk! But seeing they can't, check if tours are available to hear a few of its stories instead.
You're spoiled for sightseeing choice when staying in La Roche-Guyon. Chateau de la Roche-Guyon is a good place to start here, but there are loads of other fine places to enjoy. Claude Monet's Garden at Giverny, Monet House Museum, and Impressionism Museum are close to the fortified complex and will fill in your day nicely.
