The list is long ! On the outskirts of Paris, visit the Château de Versailles and its wonderful gardens.
A day out at Disneyland Paris is a must for the young and the young at heart !
Visit the Parc Zoologique of Vincennes (one of the biggest zoos in France), the Parc Floral of Vincennes, and its tropical garden. You can also visit the Château de Vincennes , which was first a royal residence, then a pre-revolutionary State prison, a porcelain factory and an arsenal before finally being transformed into a museum of history.
Have a nice stay !
