Railway Trail at Hardcastle Crags
The valleys of Hardcastle Crags, west of Halifax, offer stunning riverside views while the oak, beech and pine woods are full of tumbling streams.
A beautiful wooded valley with plenty to discover
Whether you decide to climb the rocky paths to the hilltops or enjoy a picnic by old weirs, there's plenty of wildlife to see.

1
Leave Gibson Mill by crossing the footbridge and turn right. Pass the weir for the lower mill pond and go up steps to walk around the upper pond. Walk carefully along the side of the river, passing the weir for the upper pond. Look across the river to the crags.
Wildlife
Look for dippers, heron and grey wagtails on the river and woodpecker, jay, nuthatch and goldcrest in the woods. Dragonflies hover over the millponds in spring and summer. Many species of fern, moss and lichen thrive in the woodlands and in spring you can see bluebells, or visit in autumn to see hundreds of varieties of fungi.
2
At the fork in the path, go left up the hill. Climb up the valley side, steep initially but soon eases. Where the path meets a wall, it levels - this was the old railway track. After a small cutting and a dip, leave the path to the left to view Hell Hole Quarry. Return to the path and continue.
The Entertainment Emporium
After Gibson Mill ceased spinning and weaving, it became an 'Entertainment Emporium' providing dancing, roller skating, teas and two restaurants. People walked here from Halifax and Littleborough for tea and a dance.
3
Shortly after going up some steps, the route turns 90 degrees to the right and by more steps. Before descending, look ahead to see the remains of the supports for the wooden trestle bridge. At the bottom of the steps is a lovely spot for a picnic. Continue back along the riverside.
Railway bridge
For 10 years, from 1902, a railway ran from Slack to the site of construction of the Walshaw Dean reservoirs, carrying men and materials. A huge wooden trestle bridge was built across Hebden Dale to carry the railway. It was demolished in 1912. Only the stone stanchions - which you can see at this point on the walk - remain. A huge shanty town, nicknamed Dawson City, sprang up at Slack to house the workers. It was said to be a lawless place ruled by two women, the Queens of Dawson City.
4
After passing a stream cascading down the opposite bank, the path turns right and uphill and then down steps. It goes up again almost immediately to meet a rough track. Go left downhill to the river.
5
Cross the river by the footbridge and go up the valley ahead to meet a rough road, then turn right. Follow the road along and through a gate to meet the road through the estate. Go downhill, passing Lady Royd Field on your left, (where local school children came to play) and then the top of Hardcastle Crags on your right. Continue on back to Gibson Mill.
Gibson Mill
The 19th-century former cotton-spinning and weaving mill now champions sustainable technology. It is not connected to the National Grid so it has to generate all of its own power and recycle its own waste. It uses solar panels and water powered turbines; even the lift works on green technology. Look out for the remains of dams and weirs which kept the valley's mills running.
