A rare chance to visit this vast, privately-owned cavern which is normally inaccessible to the public. As described in 1885 'It presents a striking and impressive scene; while a feeling of mystery is excited by smaller caves and fissures in the walls of the cavern, which although easily traced to their termination, are confidently asserted by the peasantry to lead deep into the bowels of the earth, even to the very centre of the island’.
