There are 2 trails here, with the starting point served by a nearby car park. It is also en route of the Wye Valley Trail One trail is classified as intermediary and a bit longer then the other "challenging" one. Both lead to the op of the cliff, the latter mostly by laid stones marking steps. A tough climb but the view is simply outstanding. There is also a bench and panoramic plaque highlighting what can be seen from the viewing platform. Loved it!

There are a couple of caves in this area. The first (coming from Chepstow) is very shallow and raided above the path. The second "Giant Cave" has outstanding safe viewing platform outside it, and the cave actually opens into a secondary exit allowing passage through the rock. This is a natural formation it would appear. Highly recommended!

This striking feature is a curving tunnel that is cut into the rock-face through which Piercefield Walk passes via a large opening in the southern side, and a smaller rectangular portal in the northern. It is part natural feature, and part hand-made.
