The Norfolk Windmills Trust cares for 21 buildings across Norfolk.  Thirteen are owned or leased by Norfolk County Council.

All of the Trust's mills are visible from the road and footpaths.  Most are open to the public on a regular basis or by appointment, and mills can also be opened for larger groups by prior appointment.

Special open days sometimes take place at some of the mills, and these may be advertised locally.  Volunteers are always welcome to help out at these events.

There is a small admission charge at some of the larger mills.  All donations or admission charges go towards the further restoration of mills in the Trust's care.
