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.

Carnglaze Caverns can best be found approaching from the A38 on the south side of Bodmin Moor. Follow the valley road north to St Neot off the A38 on the Liskeard (eastern) side of the shopping centre Trago Mills.There is a brown tourist sign on this junction. Follow the valley road for one mile and you will reach Carnglaze Caverns’ steep driveway on the right.
From the north turn off the A30 at either Jamaica Inn or Colliford Lake; follow the signs to St Neot village; follow the road out of the village south towards the A38 down the valley and Carnglaze Caverns is one mile on the left. Please use the turning area just past our gate as it is otherwise a dangerous, steep, tight left-hand turn. The car park is at the top of the drive.
