Cornwall Underground

Join Cornwall Underground Adventures to explore the secret world of Cornwall’s mining past. We are Cornwall’s first and only provider of authentic mine exploration in the county’s abandoned mines. Don’t miss the chance to combine a caving-style adventure experience with a first-hand look at the unique work that the Cornish miners created.

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 the 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!

Minimum age requirements based on activity, starting at 10+.
