Travel back in time as you descend into the depths at the National Showcaves Centre, a fascinating underground world of caves and beautiful rock formations that makes for a fun-filled family day out. 

There are three amazing caves to explore: Dan-yr-Ogof, Cathedral Cave and Bone Cave. For even more of an adventure, experienced caving club members can also discover the intriguing caverns and tunnels that lie beyond the areas open to the public. 


Discovered by two brave farmer brothers, and still run by the same family, this jaw-dropping cave system is around 330 million years old! The Morgan brothers followed water that was flowing from a mountain onto their land in the Bannau Brycheiniog / Brecon Beacons and discovered this labyrinth of caves in 1912. They never found the source of the river, but this discovery led to the opening of this fantastic attraction for visitors to discover for themselves. Over 10 miles of caves have now been discovered, and two other caves are also now open to the public. 

The river Llynfell flows from the mountain as you approach from the very same entrance that the Morgan Brothers made their dramatic discovery. Explore the beautifully decorated passages of Dan-yr-Ogof, and enjoy beautiful rock formations such as the ‘Rasher of Bacon’ and the heavenly ‘Angle’ on your journey.

Bone Cave

With a grizzly past, this cave is aptly named the Bone Cave due to the discovery of 42 human skeletons, which date back to the Bronze Age, over 3,000 years ago. Other precious finds were also discovered here, such as fine bronze jewellery, fragments of Roman pottery and silver rings. 

Bone Cave, or Ogof-yr-Esgyrn, is now home to some fascinating exhibits which illustrate the cave’s past uses, such as man’s struggle to survive against hyenas, wolves and cave bears - who also shared the shelter of the caves!

Cathedral Cave

Cathedral Cave, a small tunnel-like cave above Dan-yr-Ogof, is a spectacular cavern filled with breathtaking, 40-foot-high cascading waterfalls. The scene is a unique, utterly romantic location if you’re dreaming of somewhere special for a romantic proposal or somewhere to tie the knot on your big day!

The National Showcaves Centre for Wales is also home to over 220 life-sized dinosaur models and a shire horse centre! Come face to face with a Tyrannosaurus Rex and greet the massive Brachiosaurus in the dinosaur park, or meet the gentle, giant shire horses down on the farm.

Film fans may recognise this scene from the Hollywood blockbuster The Dark Knight Rises. 

Henrhyd Falls, South Wales’s tallest waterfall (88 feet), was used as Batman’s Bat Cave in the blockbuster film. The Dark Knight Rises stars award-winning actor Christian Bale, who also has links to Wales as he was born in Haverfordwest in Pembrokeshire, West Wales.

Carreg Cennen Castle

This beautiful castle perches spectacularly atop a magnificent limestone precipice within the gorgeous Bannau Brycheiniog / Brecon Beacons National Park. Head beneath it and you’ll discover a natural prehistoric cave-dwelling.  

It’s thought that the water collected in the cave once provided drinking water for the castle via a modified fissure, or natural opening, to create a safe passage and supply of water during a siege!
