We are happy to allow you to take drinks with you for immediate consumption (e.g. as provisions in your hand luggage). Beer crates, beer can pallets etc. are not permitted. On the festival site and in the town of Wacken there are plenty of shopping facilities (e.g. an EDEKA supermarket or a shopping mile on the festival site) at fair prices.
You can buy (chilled) beer and non-alcoholic drinks on the bus itself during the journey. We always negotiate with the bus companies so that we can offer a fair price for drinks (approx. €1.50 to €2.00 depending on the bus).
