This large camp occupies the summit of a rounded hill overlooking the confluence of the Afon Alwyn with the Afon Dyfrdwy, about 1½ miles south-west of Corwen and a mile north-west of Cynwyd. The defensive circuit is incompletely known. The NE and SE corner-angles and part of the SW angle have been recorded, along with "considerable lengths" of the E, W and N sides. A change in the line of the W side, which occurs roughly about the mid-point, is thought to be a gateway. Sharply sloping ground to the E would render some of the camp's interior unsuitable for the pitching of tents.
