It is often reported that Moel Sych, along the ridge, is of equal height, but Cadair Berwyn's spot height on the Ordnance Survey maps, where the trig point stands, is not the true summit. Cadair Berwyn's summit, south of the trig point, is three metres taller than Moel Sych. This summit is listed as Cadair Berwyn New Top on the Nuttall list.
