Forêt de Ferrières, Public forest in Seine-et-Marne, France.

The Forêt de Ferrières is a 2,889-hectare regional forest on the north-western edge of the Brie plateau in Seine-et-Marne, with elevations from 109 to 143 metres. Oaks (sessile and pedunculate) and ash dominate, along with lime, maple and wild cherry. Its straight rides, such as the allée du Long Boyau and route des Princes, cut the massif geometrically; the GR 14 long-distance path crosses it.

Religious communities held this land until 1829, when the Rothschild family purchased it and reorganized the domain throughout the 1800s. This change shaped the forest as it exists today.

The name Ferrières recalls the iron forges that operated in the area during the Middle Ages. Today the forest is a popular spot for mushroom picking, especially boletes, and for walking and cycling among the residents of nearby towns.

The forest is easily reached via marked roads and offers multiple parking areas at entry points for visitors. The trails vary in difficulty and suit walkers of different experience levels.

The Sika deer in the forest descend from animals introduced by the Rothschild family in the 19th century. The forest also shelters 24 dragonfly species and 300 beetle species, and its ponds and wet areas support kingfishers.
