This area of common access land is for the most part extremely overgrown and would probably be impenetrable in summer. To reach this point walk up the unmade road from the houses just west of the Trevaunance Mine chimney and after 50m turn onto the first narrow footpath which runs more or less parallel to the road. After 100m or so to the right it is just possible to see a small stack of half a dozen rocks about 10m away that someone has kindly left as a marker (if you reach a footpath branching off to the right you have gone too far, but that will take you to Pell Mine). The marker can be reached (with determination!) and sits at the top of a slope down to the large rock dump and from here it is relatively easy to reach the truly huge open excavation that runs beside the road.
