You are on an ancient packhorse track from the Long Causeway near Stiperden to Cross Stone above Todmorden. Further along the track are two farms East and West Whirlaw (now a ruin). In the days of the packhorses, one of these houses was the Packhorse Inn but after the valley roads were made in 1765 the licence was removed to the Bay Horse Inn, Cross Stone.
Once you've listened to the commentary continue with your journey.
Continue round on this causey track and down until reaching the road to a farm. Go right and follow this road downhill until the straight stretch of road by Hole Bottom.
Here is a good place to listen to the next track.
