Start in the bunker
You can visit the museum in the fire control bunker with an audio tour. Take your time over the explanations for each room. Here the construction and layout are part of what you are looking at, alongside the museum display.
A tunnel with a guide
For the Noordgang and Zuidgang, guided tours and a seasonal programme apply. So these are not spaces you can simply walk into on your own whenever the museum is open. The Noorden 2 zone is still closed due to works; bear this in mind in your expectations.
Check your chosen date
Conflicting reports about closure are circulating for this location. The museum website lists seasonal opening, but the exact hours vary by period and by part of the visit. So check the booking options for your date and, if in doubt, ask for confirmation directly.
Before you go
Book on the basis of the current museum calendar. Ask in advance about the accessibility of the dune and bunker site.
