Here, the 110 hectares of wild land and two small lakes harbour crickets (Euchorthippus elegantulus gallicus), wall lizards, and goblet-marked damselflies. Some of these insect species are rare in Ile-de-France and the park was set up to protect them.

Set off on foot or on bicycle to explore the diverse habitats (wetland, shrubs, grasslands alluvial beach and so on) and stop off at the Maison des insectes to learn more about the grass-dwelling creatures. This 800 m² space has a fun and educational exhibition area where you can observe living insects in a number of vivariums as well as a butterfly house. It also organises workshops, events, field visits and film screenings.

The keenest nature lovers will book ahead to do some birdwatching from the Observatory that sits 13 metres high overlooking La Galiotte lake.

Great for families: the free “Balade branchée” app (designed by the Office national des forêts, the IDF ‘green space’ office, and the Seine-et-Marne and Les Yvelines départements) which suggests different ways to discover natural sites in Ile-de-France and includes a fun discovery trail guided by superheroes Tom and Zoé. There are also games pitches (French boules, basketball) and a picnic area.
