About
Carnglaze Caverns is a hidden gem in Cornwall, offering an unforgettable underground journey through a 300‑year‑old slate mine. Visitors wander 150 m into the hillside to explore three caverns, including a floating lake, guided by safety helmets and a detailed narrative of Cornwall’s mining heritage. A 20‑minute woodland walk enriches the experience, featuring ancient oak trees, wildlife and, in spring, a carpet of bluebells. With seasonal Winter Wonderland events, car parks, and a range of activities like concerts and wedding venues, Carnglaze blends history, nature, and adventure in one accessible destination.
