The most important public green space is the Plage Bleue Park where different events are organized every year.

Valenton is surrounded by the towns of Choisy-le-Roi, Créteil, Crosne, Limeil-Brévannes, Villeneuve-Saint-Georges and Yerres.

The town extended in 1936 with the construction of two new residential areas (Les Vignes and Val Pompadour).

The town which was a strategic point during the Second World War was heavily bombarded by the Anglo-American aviation, which caused many casualties among the civil population.

The aim for this heavy pounding induced by this air raid was to destroy the strategic marshalling yard of Villeneuve-Saint-Georges close to the Val Pompadour residential area.

It is organized in the municipal central park (Parc de la Libération) and it lasts a whole day.

It was initially an agricultural area for market gardening at the beginning of the 20th century thanks to its fertile soils.

The project won urban planning prizes in 1993 and 1994 rewarding its focus on environmental issues.
