A hillfort set upon a rocky spur which juts out S from the Great Orme.

On the NW are three lines of defences; the outer two are set at the bottom of the slope leading up to the hillfort, and consist of two scarp slopes. The inner defence is a stone bank or wall built at the top of the slope. The plan in Lowe, 'The Heart of Northern Wales', shows most, but not all, of this.

The inner wall can be traced round most of the W side, starting just NW of the rocking stone, around the N side, and half way down the E side. The outer defences are now best preserved on the NW, and may continue around the hill as far as the limit of the inner bank. They become confused on the N and cannot be traced on the NE. On the NW the outer face of the outer scarp has been dug away, probably in the 19th C, and a stone revetment wall 1.8 m high built against it, to form sheep pens or paddocks.

At one point the wall diverges from the scarp, and a clear profile is visible. S of the paddocks the outer scarp may be marked by a sharp break in the slope of the field W of the fort (Lowe marks this as the route to the main entrance). The inner scarp may continue under the modern field wall, or it may run to the E of this.

On the N the outer scarps have recently been disturbed by the creation of a car park, and they are no longer readily definable. A path running through the trees also confuses the remains. There may be an undisturbed section immediately S of a small shelter built on the edge of the adjoining ski run.

Above the disturbed section, the inner wall has been broken through in two places by modern paths; the more W of these breaks may mark the site of an entrance. There is a number of round huts in the interior. Those identified by the OS are clearly visible, but others lie against the inner bank, and there are more to the N. Without excavation it is not possible to differentiate with certainty between natural hollows and the terraced hut sites.

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.
