Tours Underground in Cornwall’s Carnglaze Caverns

There are three chambers of cathedral proportions, hand created by local slate miners. During your tour you will go about 150m into the hillside and 60m below ground, via a flight of 60 steps. In the lower chambers you will find the Underground Lake with its crystal clear blue/green water.

For much of the year you will be equipped to go on a self-guided tour of the three caverns but in high season guided tours may be in operation as there is a limit on numbers allowed in the lower caverns at one time.

The Caverns are at a constant 10°C, so a jumper and sensible footwear* are recommended.

* Flip flops are deemed sensible, if you wear them regularly!

Opening Times for Carnglaze Caverns

Open all year Monday – Saturday 10am-5pm (8pm August)

Please note – we are closed Christmas Day but may be open Boxing Day and New Year’s Day. Please phone to check.

Coach Parties and Group Tours

We welcome group bookings for a guided tour by prior arrangement, including evenings and Sundays, throughout the year. Groups of 20 or more, paying as one, attract a 10% discount. These have proved to be especially popular with classic car groups enjoying a Sunday afternoon drive, and with special interest groups.
