The quarry has gated this cave (May 2007) and access is being negotiated.
The entrance is behind the Tynant Inn and about 7 metres below the top of the hill. Situated in Garth Wood which is marked on OS maps. At Morganstown, just off the A470 near Taff's Well, a footpath behind the Tynant Inn leads past the allotments to the woods. Climb straight up the hill and the entrance is near the top in a shallow depression. Not easy to spot until you are right on top of it.
See the Access p.of the Cambrian Caving Council Website for current Access arrangements at http://www.cambriancavingcouncil.org.uk/cave_access.html
An interesting and well decorated cave which lies very close to the active quarry.
A wide entrance leads to a ledge. There are three places to climb down from this ledge to the lower passage, which contains a short oxbow at the end. The cave may be lost due to quarrying.
