About Cornwall Underground Adventures

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 tine 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 offer the Underground Explorer, a perfect introductory, walk-in, walk-out trip through several levels of an ancient tin mine. This trip includes some tight spaces and there is an option to do a small abseil, to get a flavour of more advanced caving techniques. Adventure enthusiasts and adrenalin junkies will want to opt for the Underground Adventurer. This is a challenging through-trip, requiring a head for heights, as abseiling and traversing deep shafts and chasms is essential to complete this underground journey. Please take some time to browse our website, photos and videos to make sure you select the perfect adventure for you and your group, before booking.
