 The cave was used as a show cave many years ago, but it does not have the attractions of more decorated caves such as Dan yr Ogof, and so today the cave is more often used to introduce people to the enjoyment of the exploration of caves.Entry to Porth yr Ogof is most often made through the wide Main Entrance, either using a dry ledge on the left or by wading through the knee-deep river to the centre and right.The second most used cave entrance is called the Workman's or Tradesman's Entrances.
