The Story of Cathedral :Tunnel Cave 

Cathedral Cave is the name for this famous showcave in Wales. Cavers call it Tunnel Cave and can explore over the 2 km of extremely difficult passages that carry on from the end of huge chambers accessible to the general public. This film provides both non-cavers and cavers with a detailed description of how the cave was discovered and what it is like to explore the complete strenuous system right to the very ends (there are several) , one ending in a beautiful grotto and one following vertical shafts up onto the mountain above the cave. This is a full fascinating story for anyone who has or intends to visit the cave.
