Camp, on Penyffrwdllwyd, near Ystrad Meurig, is a D-shaped earthwork. The area is enclosed by two crescentic ramparts resting on a line of precipitous crags. This is one of the highest camps in the area. The fosse on the N.E. has been excavated from solid rock. An excellent view of Pendinas and the Ystwyth Valley can be obtained.
