We got booked on at short notice. The group was quite big and included three dogs. They did not seem upset by the dark fortunately, but didn’t appreciate the tour guide’s humour. Of course this was the ideal place for some Halloween themed added decorations but included in the first part of the tour about early cave dwellers and who else sheltered or hid there, it emerged that the Cavern gets it’s name from a villain who is said to have died in here and haunts it. (No ghosts appeared on our tour.) Our guide used his torch to highlight various formations, some needed a bit of help to explain their names, for instance “the wedding cake” wasn’t tiered but the two stalagmites on the top had been thought to be like the bride and groom in the top of a cake. Our guide also altered the lights of the cavern to show different aspects and finally in the deepest part of the cavern, switched all the lights off so we could see how dark it was with just a flame from a lighter and no light pollution, or moon or stars. He then demonstrated what real darkness was, when the lighter disappeared inky black with no chance of seeing your hand before your face or your eyes adapting to the complete blackness.
