Château Vaux-le-Vicomte is a wonderful day trip from Paris. It's remarkably peaceful and tourist free. You can stroll the gardens and even bring a picnic that you can enjoy on the back lawn. Afterwards, explore the château built by the ill-fated Nicolas Fouquet, Louis XIV's finance minister. The 17th century baroque palace is one of the most beautiful in France. The young king became jealous and suspicious of Fouquet's wealth and had him imprisoned (he also brought the three artists who worked on the project together to do Versailles) Luckily, Vaux-le-Vicomte has gotten easier to get to from Paris. Take a train from Gare de l'Est to Verneuil l'Etang. Shuttles are timed to pick up visitors to take them to the château right after the train arrives. The entire trip takes about an hour.
