Visit this former slate mine where slate was both quarried and mined underground in Cornwall. Carnglaze is affiliated to the Cornish Mining World Heritage Site as members of the Cornish Mining Attractions Marketing Association. Find out about the miners’ ingenuity and skills, and how slate roofed the Industrial Revolution.

You will go on a self-guided underground tour (may be guided in high seasons) to learn how the mine was worked, ending at the Underground Lake with its crystal clear blue/green water. Browse the comprehensive collection of minerals mined and quarried in the South West, after which you will descend a flight of 60 steps taking you about 150m into the hillside and 60m below ground.

Carnglaze Caverns is a constant 10°C underground, cool in Summer, warmer in Winter! A jumper and sensible footwear are recommended. As the Caverns are underground it makes for an ideal wet weather activity in Cornwall.
