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.

This pretty, wooded area with its network of small caves - the result of former quarrying - is a nature reserve with a rich variety of flora and fauna. Horseshoe bats and rare invertebrates such as the cave spider and hibernating herald moths make their homes within the caves.
