Worksite visits will be arranged every 30 minutes. They will include two stops* (reservation is mandatory):

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

Visitor Centre hours: 09:30 to 17h30.

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 departure point. From there it is a short walk to the Visitor Centre (closing time: 17:30).

Shuttle buses will leave approximately every 10 minutes from in front of the worksite cafeteria to bring you back to your cars in the parking lot.

*Refreshments and snacks are available for purchase.
