Dan yr Ogof caves are located at the National Showcaves Centre for Wales, a 17-kilometre (11 mi) long cave system in south Wales in the Upper Swansea Valley, Brecon Beacons National Park. The first section of the cave system is open to the public, but the extensive cave system beyond is scheduled as a national nature reserve and is open only to bona fide cavers.
The bones of some 42 humans, as well as numerous animal bones, have been found in one of the nearby chambers of this cave system. In a 2005 poll of Radio Times readers, Dan yr Ogof was named as the greatest natural wonder in Britain. The cave was used as a filming location for the Doctor Who serial The Pirate Planet.
There are ten attractions all included in the one National Showcaves Centre entry ticket, including a dinosaur park, iron age village, and shire horse centre. There is plenty to see and do for all ages. I suggest that at you allow a few hours for a visit and with lots of covered areas its an ideal attraction for a rainy day. The 3 different caves Dan-yr-Ogof, Cathedral Cave and Bone Cave each offer a unique underground experience. About 1 km of underground passageways are open to the public, including the huge Cathedral Cave with its underground waterfalls.
A small tunnel-like cave above Dan-yr-Ogof Farm has been known for many years. When you look over the railings at the entrance to Cathedral Cave you’ll see the beginning of this tiny passageway through which members of the South Wales Caving Club squeezed in 1953 to make the most awe-inspiring discoveries.
To their amazement, after blasting their way through boulders to the end of this small tunnel half-filled with water, they came upon a colossal cave passageway, decorated with thousands of delicate ‘straw’ stalactites. Waterfalls cascaded into underground lakes, and unusual formations adorned the cave walls. This was the beautiful cavern we now know as “The Dome of St. Paul’s”.
Cathedral Cave and its wonders are now viewed by thousands of people from all over the world every year, and it is regularly chosen as the most spectacular venue for a wedding!
