Our Climb The Mine activity is the perfect indoor climbing adventure for a rainy day! Climb the Mine follows the route of the original underground mine workings and is complete with vertical climbs, rope-bridge crossings, steel ladder ascents, run-away zip line and a Tarzan swing. You’ll be able to explore a secret world of hidden passages and magnificent cathedral-sized caverns where miners used to extract rock for roofing slates, before emerging to a spectacular view of one of England’s highest mountain passes.
