Hardcastle Crags

Hardcastle Crags is a wooded Pennine valley in West Yorkshire, England, owned by the National Trust.

[1] It gave the title to a poem by Sylvia Plath that was included in her 1960 debut collection The Colossus.

[3] The mill was water powered and has been renovated to demonstrate renewable energy sources and a sustainability strategy.

It is surrounded by 400 acres (1.6 km2) of unspoilt woodland and crossed by 30 miles (48 km) of footpaths.

Water powered turbines, photo voltaic panels, composting toilets, a wood-burning boiler, a wood-burning cocklestove and locally sourced reclaimed interior materials have gone into making the venture sustainable.
