Paris, City of Light with London Extension

France’s aristocrats began building defensive castles in the Loire Valley in the 11th century. A few hundred years later, their descendants created pleasure palaces among the lush green forests and wandering waterways. Today, sumptuous Renaissance castles stud the banks of the silvery Loire River, the longest in France. But few castles can compete with Château de Chenonceau. Built on a series of arches over the Cher River, Chenonceau was designed by a woman in the 16th century. It was once inhabited by Catherine de Medicis, who commissioned the delicate spirals and of the formal gardens, and had the bridge covered by a two-story stone gallery. You’ll also visit Château Chambord, the largest and most lavish of the Loire châteaux (and that’s saying a lot). It took 1800 workers over a decade to complete the palace for King Francois I, who once suggested that the river be diverted to make a moat (a smaller river was later diverted). The palace has 440 rooms, and in many of them you can see Francois’ salamander emblem—reported to have been an appropriately slimy symbol for the king. Stop to see Chartres Cathedral. Built on an ancient worshipping ground to house a piece of the Virgin Mary’s veil (which is still on display), this 13th-century Gothic church is best known for its windows. With over 20,000 square feet of stained glass, visiting Chartres can be like walking around inside a large jewel. But don’t spend all your time looking up—on the floor is the only surviving medieval labyrinth. The faithful travel the winding 300-yard path on their knees to reach the image of paradise at the center. Ouch

Claude Monet discovered this tiny farming village when he looked out the window of a stopped train. Impressed by its beauty, in 1883 he and his family moved into the pink stucco house where he spent the next 40 years planting his extensive gardens and creating some of the world's most beautiful Impressionist paintings. Spend some time wandering through the riot of natural color in the Clos Normand and watching soft light shine on the delicate Japanese bridge and lush water lilies that inspired some of his most famous works. See Monet's studio, preserved just as he left it, with supplies and sketches scattered around. Neglected for years and badly damaged during WWII, the house and gardens took 10 years to restore, but are now back in their full glory. Which just leaves one question: With all that weeding and fertilizing, how did Monet have time to paint?
