Can I connect to the mains electricity supply at the campsite?

Campervans wishing to connect to the electrical grid must purchase the "electricity" supplement. To connect you will only need an extension cord of 20-25 m. with CETAC plug. If your extension is Shuko you will need to bring a Shuko to CETAC adapter.

If you do not have this material, you can rent an extension cord or an adapter at the Camper area ticket office.
