#1 Chantilly Castle (Chantilly)
Located 25 miles from Paris, Chantilly Castle houses the Musée Condé, the second largest collection of antique paintings in France. This 284-acre estate features gardens by Le Nôtre, monumental princely stables, and equestrian shows. It is more intimate and less crowded than Versailles, with every displayed work being an original that never leaves the premises.
