Petit Etang Neuf

Petit Étang Neuf is a small, quiet forest pond tucked deep inside the Rambouillet Forest, in the commune of Poigny-la-Forêt in the Yvelines department, in the Île-de-France region. It sits within a protected natural area and forms part of the Upper Chevreuse Valley Regional Nature Park, which combines scenic value with an ecological role for local wildlife and plant life.

Where exactly is this pond located?

The pond lies at the heart of a large forest complex that has long served as hunting and recreational grounds for people living around Paris. Poigny-la-Forêt is a small rural commune completely surrounded by woodland, and Petit Étang Neuf sits right next to another body of water, Étang Carré. The two ponds are close enough together that they are usually visited during the same walk.

What can visitors do here?

The main reason people come to Petit Étang Neuf is hiking. A loop trail of roughly 5.5 kilometers runs through the area, rated easy and typically completed in under an hour and a half. The path winds through the forest and passes both Petit Étang Neuf and Étang Carré, letting walkers see both ponds on a single outing. The spot is also used as a rest point along a longer, multi-kilometer hiking route starting from Poigny-la-Forêt — after a stretch of walking through the forest, the pond offers a natural place to pause, catch your breath, and enjoy some water scenery.

The area is popular with people seeking quiet and a genuine connection with nature: dense forest cover, no buildings, and light foot traffic make it an easy escape from city noise. Trail runners and cyclists also make use of the network of forest tracks that cross the surrounding woods.

Does this place have any other significance?

The picturesque setting of the pond and the forest around it has occasionally attracted film crews — the Yvelines region, thanks to its proximity to Paris and its largely untouched, forested landscapes, has long been a convenient location for productions looking for woodland scenery without traveling far.

The area's protected status means the site is subject to specific conservation rules; it forms part of a wider network of natural areas shielded from heavy development, which helps preserve the character of a wild, forest-fringed pond.
