In the middle of the Hardcastle Crags woodland sits Gibson Mill, a National Trust attraction that combines social history with applied sustainability. The mill operated from 1800 as a cotton spinner, later became a Victorian pleasure ground with a dance floor and roller-skating rink, and now houses exhibitions on its three lives plus a café fuelled entirely by on-site renewable power.
The walk in from the Midgehole car park is about half an hour each way along the wooded river — there is no vehicle access for visitors. Open seasonally; check the Trust website before visiting.
