Cornwall Underground Adventures is offering adventurous caving trips in Cornwall's abandoned tin mines. Are you looking for interesting and exciting things to do in Cornwall? Then why not combine Cornwall's mining heritage with an exciting adventure underground? You can now experience the thrill of mine exploring with our experienced guides. Go below the surface and discover the subterranean world carved out by the Cornish miners over hundreds of years. The miners have long since vanished, but their legacy is a world beneath your feet, waiting to be discovered.

We are based in west Cornwall and all of our activities currently take place near the old mining district of St. Just. We are within easy reach of St. Ives, Penzance and Sennen Cove, and not too far from other popular tourist resorts, such as Newquay, Falmouth and the Lizard Peninsula. We offer something for everyone, and our underground activities are perfect choice, come rain or shine.

Our mine adventures range from easy walk-in, walk-out trips, to full-blown caving-style trips. Explore the complex systems of tunnels that make up a Cornish mine. Marvel at how the miners shaped these places, and gaze in wonder at the features of this hidden world. Those seeking a thrill can try abseiling down mine shafts, crossing gaping chasms and flooded passages, underground via-ferrata, mine climbing and more!

Our surface tours are perfect for those interested in the history of Cornish mining but don’t want to venture underground. Evidence of Cornwall’s mining past is an integral part of the county’s landscape. The old engine houses are one of Cornwall's most iconic features. Famous landmarks include the Crown Mines at Botallack, Wheal Coates at St. Agnes, as well as several mining museums, such as Levant Mine and Beam Engine and Poldark Mine. The vast sites of Geevor tin mine and South Crofty, the last mine to close in Cornwall, still loom over the landscape.

But almost every cliff, cove and carn has a hidden mining history, not always visible to the untrained eye. Our expert mine historians take you on a guided walk around an area rich with mining archaeology. Be amazed as these open-air mining museums bring the story of Cornish mining to life. Learn facts, history, and tales of adventure and tragedy that would have been the envy of Ross Poldark!
