Craig y Forwyn (Maiden's Crag) is a crag that encloses the northern side of World's End, near the town of Llangollen in Denbighshire, Wales. It is part of the limestone escarpment that separates the Eglwyseg Valley from the higher Ruabon Moors and, along with nearby Craig Arthur, is a popular site for rock climbing. Evidence of lead and silver mining is found just to the west. The Offa's Dyke Path runs along its foot.
