This weekend Historic Scotland are letting you access their properties for free, so I thought it would be an ideal opportunity to have a trip along to Stanley Mills at Stanley (15 minutes drive) It is a huge complex of old mill buildings, part of which have been converted into flats. The mill is right beside the River Tay. The visitor centre has been very well done, interest for all ages and very hands on in places. They have a fantastic water display where you work sluice gates and wheels etc, great fun. Stanley Mills is open all year, so pop along.
