Carnglaze Caverns

If you make a visit to Trago Mills then make sure you find time to visit Carnglaze Caverns, which is very close by. I think this is the country’s only visitable underground slate mine. You can find out about the miners’ ingenuity and skills, and how slate roofed the Industrial Revolution.

A self-guided underground tour about 150m into the hillside and 60m below ground shows you how the mine was worked, ending at the Underground Lake with its crystal clear blue/green water (from which the house above draws its water).

The first of the three caverns, the Rum Store, was one of the nation’s safe storage areas during WW2. It is now used as a 400 capacity concert and event venue with outstanding acoustics and atmosphere with a wide range of musical entertainment and events throughout the year. It is also an unusual wedding venue for both ceremonies and receptions!

The caverns are a constant 10°C underground – a jumper and sensible footwear are recommended and as the caverns are underground it makes for an ideal wet weather activity. There is also a woodland trail that takes you around one side of what was once a quarry. Look out for fairies in the Enchanted Dell!
