Situated on open hillside to NE of Llyn Nantlle Uchaf, the fort is on a rocky knoll which forms the W end of a small ridge. The enclosure is of irregular shape of c. 30m in diameter and surrounded by dry stone walling of large slabs which is about 2.5m in thickness with a slight batter on both sides. Externally it stands to about 1m in places, but internally it is mostly levelled. There is a much ruined entrance on the W side.

The monument is of national importance for its potential to enhance our knowledge of Prehistoric settlement and defence. It retains significant archaeological potential, with a strong probability of the presence of associated archaeological features and deposits. The structures themselves may be expected to contain archaeological information concerning chronology and building techniques.

The scheduled area comprises the remains described and areas around them within which related evidence may be expected to survive.
