The monument consists of a cave containing archaeological deposits, dating to the palaeolithic period. Hoyles Mouth Cave lies about 22m above OD, on a rocky ledge overlooking the Rhydeg Stream to the north. The northern facing entrance is 3m wide, 4m high and opens into a main cavern c. 6m deep, from which a narrow tunnel leads further into the limestone. Palaeolithic and Mesolithic flint has been uncovered from excavations, as well as reports of metal objects, now lost. Human and animal remains were discovered.

The monument is of national importance for its potential to enhance our knowledge of prehistoric settlement, ritual and funerary practices. It retains significant archaeological potential, with a strong probability of the presence of associated archaeological features and deposits. The scheduled area comprises the remains described and areas around them within which related evidence may be expected to survive.
