The former mining landscape near Grassington makes an interesting area for a walk. Take the road north-eastwards from Grassington High Street towards Yarnbury. If you are in a car, just keep going till you run out of tarmac road. There’s plenty of room to park at the end, so don’t worry.
Around here is Yarnbury House, which was the mine agent’s house and office. Head along the track in the direction of the chimney, which can be seen in the distance to the east. Look out for noticeboards describing relics of interest. The track passes an area dotted with shallow shafts, and other relics including a post-war reprocessing plant. As you approach the chimney and leave the track, you should encounter the long horizontal flues running from the smelter sites up to the chimney. The structure of the flues can be seen in places where they have collapsed.
You should take with you a map that identifies the various relics, so that you can check out any that are on your line of walk. The tracks continue southwards to Hebden Moor mines and Hebden village. If you go far enough to the north-east, you will reach Mossdale (use a map). If you don’t want to retrace your steps, satellite pictures indicate that taking a left at a crossroads near Coalgrovebeck Dam will loop you back to Yarnbury, passing 3 more disused mines.
