Access to the exterior is generally free. For interior access or guided tours, specific fees may apply, often by donation or a modest charge.
Viewing the Central Nissewaard Windmill from the outside is free of charge, as it is a prominent local landmark. For interior access or during special opening days, there might be a small entrance fee or a request for a voluntary contribution to support the mill's maintenance and operation.
Information on specific costs for internal visits or guided tours should be checked on the official website of the local municipality or the mill's managing foundation, as policies can vary. During events like National Mill Day (Nationale Molendag), access is often free or for a minimal charge.
