1953 first explored by members of the South Wales Caving Club.
1971 at Easter opened to the public.


Cathedral Cave is above Dan-Yr-Ogof Cave. This cave got its name because of the huge chambers the Dome of St. Paul's. Beneath its size, it has many interesting formations, lakes and waterfalls.

The cave contains tableaux scenes of cave dwellers and their lives. In several scenes the daily life of our anchestors is shown.

Cathedral Cave is also available for weddings. This kind of cave usage is very common in the USA, but this cave is the only one in Great Britain we know of.

The cave was originally discovered in 1953 by members of the South Wales Cave Club who had to crawl along a low passage half full of water before climbing up through boulders into the entrance hall. However, today, the visitor is spared all this. The cave management have drilled an 8-foot square tunnel into the main passage and laid a wide concrete path for nearly a thousand feet into the mountain. For most of its length the passage is an average of 20 feet high and 30 feet wide, presenting a tremendous spectacle, equalled only in some of the continental caves. The 1000-watt quartz-iodine lights illuminate the passage and show up formations in the roof which were missed by the early explorers. At one point the roof is illuminated to refiect into a small lake, whilst adjacent to this is a display of local minerals and fossils, including a drip-pocket - a calcite-lined hollow beneath a drip from the roof - which is a special feature of this cave.

Cathedral Cave and Dan yr Ogof are caves of contrast, the former notable for its grandeur, the latter for its beauty. See the latter first!
