Very impressed with our visit to Wheal Martyn China Clay We arrived on Sunday 5th May,on paying I asked if there was a guided tour and a member of staff who was about to just walk his dog volunteered to give us a tour in his own time, he even had roast lamb waiting in the oven! Nothing was too much trouble, he kept us entertained with stories of interest, and personal stories about his own father. A very interesting and informative visit that kept us occupied for hours. A lot of effort and love goes into the displays by staff and volunteers. Afterwards we visited the café which was very clean and had local Cornish pasties, all of an excellent standard. It is also worth mentioning that the loos were new and spotlessly clean.
