Lumsdale Mills, Ponds & Waterfall 2026

The valley is one of the best water-powered industrial archaeological sites in the UK; it is unusual to see so extensive a use of water power, from before the 17th century, in a relatively small area. The mills were powered by Bentley Brook using a series of holding ponds and leats. All the mills except the Bone Mill are situated in a wooded gorge with a waterfall. Some areas around the mill ruins have been fenced off for safety reasons. Please do not go into the fenced off areas, as this is for your safety, and to ensure the future of the historic ruins.
