Porth Yr Ogof - gateway to the cave, in Welsh - boasts the largest entrance of any cave in Wales at over 55 feet (17 metres) wide and almost 16 feet (5 metres) tall. The cave is managed by the Brecon Beacons National Park Authority and is adjoined by a visitor centre and a pay and display car park, which is a handy place to park to explore the waterfalls.
