Parc Balbi, English-style park in the Saint-Louis district, Versailles, France

Parc Balbi is a classified historical monument and park in the Saint-Louis district of Versailles. The roughly 25,000-square-meter space is crossed by a stream leading to a grotto, while the surrounding area is filled with naturally arranged groups of trees creating woodland-like pockets.

In 1785 the Count of Provence, later Louis XVIII, bought plots beside the Potager du Roi and had Jean-François-Thérèse Chalgrin lay out an irregular pleasure garden for meetings with his mistress Anne de Caumont La Force, Countess of Balbi. After the count fled in 1791, André Thouin moved rare plants to the Jardin des plantes in 1792. The river was filled in around 1842, and the grotto opened to guided visits in autumn 2005.

The park reflects how late 18th-century garden design favored natural arrangements over rigid symmetry, mixing tropical and native trees in flowing patterns. Visitors can see how this approach created spaces that feel less formal and more like wandering through a carefully composed woodland.

The park is located on Rue du Maréchal Joffre and accessible throughout the day with adjusted schedules depending on the season. It is best visited in dry conditions since walking paths wind through green areas, and comfortable footwear is recommended for exploring the ground.

The grotto was reopened to the public only in autumn 2005, after two students of the École nationale supérieure du paysage, Céline Batisse and Julien Decker, began restoring it and its surroundings in 2004. On Sunday 7 October 2007, during the Versailles and the King's Kitchen Garden flavours event, 1,200 people visited the grotto and its surroundings.
