    Practical Details

    When you arrive at ITER Headquarters in Saint Paul-lez-Durance, proceed to the staff parking lot to park your car.

    Go to the reception building in order to proceed to the access formalities.(passports (ID cards for EU citizens) and a printed ticket will be mandatory for each visitor).

    Shuttle buses running approximately every 10 minutes will take you to the worksite cafeteria*, the departure point for the one-hour tour of the worksite (buses leave approximately every 30 minutes). From there, it is only a short walk to the Visitors Centre with its exhibits and guides.

    Visitors should be appropriately dressed for the worksite tour—flat, closed shoes and no skirts, shorts, or dresses.

    We will provide mandatory safety equipment for all participants (hard hats and visitor vests).

    At the end of your tour of the worksite, the buses will return you to the exhibition area should you want to enjoy it a little longer (closing time: 18:00).

    Shuttle buses will leave approximately every 10 minutes and bring you back to your cars in the parking lot.
