Well apart from the obvious (Disneyland!) here is a run down of other things to do in the area:

 

Between the Marne to the north and the Ferrières forest to the south, the urban development of Marne-la-Vallée continues to be carried out with concern for the protection and value of natural areas.

There are many opportunities to discover this conserved region: hiking trails and cycle tracks traverse the many wooded areas where the Marne and other streams run.

2000 hectares of parks are accessible to everyone.  The development of 58 lakes and above all the entertainment base of Torcy enable the practice of water sports.  Marne-la-Vallée benefits from a huge range of sports equipment including two golf courses.

 New town, Marne-la-Vallée is no less than a historic town.

Châteaux (Ferrières, Champs-sur-Marne), old Brie farms or museums, there are several vestiges of a flourishing past.  The municipalities take care to protect them and value them for the greater enjoyment of visitors: the tourist trails lead them to the discovery of Marne-la-Vallée's hidden treasures.  The old Menier chocolate factory in Noisiel is an emblem of the heritage of the industrial revolution.

 

And of course you have the Val d`Europe which is a huge under cover shopping centre complete with a sea life centre.
