My parents live in Cornwall, so I often have the opportunity to see another of the 10 subsites. To date I have visited five of them.

St Just Mining District - in the far west of Cornwall you will find this is one of the most photogenic parts, with derelict mineshaft pumping stations clinging to the rocky coast. I suggest heading to the Count House at Botallack and walking from there.

The Port of Hayle - near to St Just, much less picturesque. This was an industrial centre, and you can see the remains of a foundry and millpond.

Gwennap Mining District with Devoran and Perran and Kennall Vale - a good way to see this subsite is to cycle the 11 mile miners' track. It takes you through quarry 'valleys'.

Tregonning and Gwinear Mining Districts with Trewavas - a split subsite: the main part is to an area of hilly heathland with good views from the top. Several miles away is also inscribed the village of Rinsey, where - like at St Just - you will find picturesque cliffside mine buildings.

Tamar Valley Mining District with Tavistock - this site is in the far east of Cornwall, where it borders Devon. Again, it is a split subsite, with one part featuring Kit Hill (very windy when I visited) and the other referring to the town of Tavistock (technically in Devon). It is a handsome mining town that was prettified by the 7th Duke of Bedford.
