The friendly staff and pleasant woodland walks are also frequently highlighted as positives, making it a great value day out for families and explorers alike.
"Our visit to Carnglaze Caverns was great. Even without a guided tour, we found plenty to explore and enjoy at our own pace. It doesn't take too long to get round.
The caverns are fascinating cool, vast, and beautifully lit to highlight the natural rock formations and the incredible man-made spaces carved out over the years. The Subterranean Lake was especially breathtaking, with its crystal-clear water. I loved seeing the LP cover shown where the photo was taken on the lake.
Above ground, the woodland walk is a lovely addition to the visit. The trail is well signposted and has quirky sculptures and little surprises along the way. It’s a great way to enjoy the natural beauty of the area after spending time underground.
Obviously there are a lot of steps and uneven ground. Wear good shoes.
Everything is well maintained, the staff were friendly and welcoming, and the whole experience felt relaxed and unhurried.
Nice little tea shop to relax after your visit."

"What a fantastic day out. Prices were £36 for 2 adults and one child. But this was at the option you could come back anytime throughout the day. The cave was fantastic. All the lights to colour up the cave were amazing. My son loved the whole experience. Great for a rainy day as well"
Chloe Oxford
"A lovely place to visit on a hot day. All the staff were very friendly. The caverns were interesting but there wasn't a lot to see. The woodland walk was lovely.
All in all it was a mornings visit but for the price £20 for 1 adult and a 15yr old it was good value."
