The scope of the Cornwall and West Devon Mining Landscape can seem rather daunting, with its multiple components, but after my visit last May, I felt I had a better understanding of its role in the Industrial Revolution. I appreciated the recommendations of other reviewers on this site to help focus my travels, and used the quaint town of Tavistock as a base for my two day tour. From Tavistock, which is well described already, I followed its canal south to the Victorian river port of Morwellham Quay. This open air museum includes a copper mine, a village with a large water wheel used to crush manganese, and a quay once famed for the amount of copper transiting through it. Similar to Morwellham was the atmospheric port of Charlestown, where fog was rolling in over tall ship replicas when I arrived. This coastal harbor in southern Cornwall was also used to transport the region's copper out to the world. Some of this copper ore was shipped north to the Welsh port of Swansea, which, thanks to its nearby coal reserves, became famous as a copper smelting city in the 18th and 19th centuries. One can easily enjoy touring Cornwall and Devon with no knowledge of this World Heritage Site, but I really appreciated learning about the region's mining history.
Logistics: I found it easiest to visit sites via a rental car, since there are so many sites spread out across the region. In addition to Tavistock, Morwellham Quay, and Charlestown, I heartily recommend the Gwennap Pit and photogenic Wheal Coates, a former tin mine in the St Agnes Mining District.
