Leisure, tourism and major venues: investing in Val-d'Oise

On the edge of Paris and around Paris-Charles de Gaulle, the busiest airport in metropolitan France by passenger numbers, Val-d'Oise welcomed 14.1 million tourists in 2025. This page gathers the official figures that matter to the promoter of a leisure park, a major venue or a tourism project.

“Developing high-profile tourist attractions” (« Développer les attracteurs touristiques à forte visibilité ») is the first of the five priorities of the Department's tourism strategy, presented in 2024.

Triangle de Gonesse: the official position

  • The Europacity project was abandoned by the French State on 7 November 2019. (Présidence de la République, Ecological Defence Council)
  • The programme considered by the public developer comprises the Grand Paris Express station, an international school campus, the national centre for street arts, a sports facility, then economic activities made up “mainly of productive activities, plus some office schemes”. “The project and its programme are still being defined.” (Grand Paris Aménagement, page updated 4 November 2025; quotations translated from French)
  • The Île-de-France Region, which is building the international school campus, announces its delivery for the start of the 2029 school year; the developer's page still shows September 2027. (Région Île-de-France, published 31 August 2026)
  • This programme does not include a leisure park: the area is not put forward here for a project of that kind.

The steps of your project

Developing an amusement park, or a play and sports area, of more than 2 hectares requires a development permit (permis d'aménager), issued by the town hall.

Places that already draw visitors

Among its strengths, the Department lists tourist attractions that generate “visitor flows, spending and image, in particular: Auvers-sur-Oise, La Roche-Guyon, the Vexin Français Regional Nature Park, Enghien-les-Bains and Royaumont Abbey”.

Sources: Val d'Oise Tourisme, presentation of the departmental tourism strategy (published online May 2024) for the quotation, translated from French; 2025 key figures (brochure, May 2026) for combined attendance, which notes that growth at leisure facilities was driven in particular by the Casino Barrière and the Cergy-Pontoise leisure island.
