Only a couple of miles from Rochdale town centre, Healey Dell is in dense woodland on the tight banks of the tumbling River Spodden.

Here the river has hewn a sharp gorge, and bubbles over rapids and waterfalls that once drove, corn, wool and cotton mills.

Best of all though is the Victorian viaduct spanning the gorge.

This was built in 1867 for a long-defunct railway and is a fantastic viewpoint 30 metres over the river.

Faint traces of industrial archaeology await along the river at what’s left of the Broadley Wood Mill, Stone Rubbing Mill and Th’Owd Mill l’th Thrutch.
