The Brecon Beacons National Park can boast impressive natural caverns and subterranean passages in Great Britain. The underworld area extends for over ten miles underground. Lots of experienced cavers, as well as novices, explore these caves. Archaeological excavations (more then 40 human skeletons have been found in the caves) indicate that in the Bronze Age people live there and buried the dead here.
The most impressive is the Cathedral Cave, located 150 m under the ground and is 10 m high. By the way, it is a favourite place for marriage ceremonies! Visitors can go through safe pathways in the caverns, admiring the stalagmites and stalactites in different forms. During your walk, music echoes through the caverns and creates a romantic mood.
You can visit the Dan Yr Ogof caves from April to October in the daytime.
