One of the very few potholes in Wales. This one has several passages at different levels with some fairly good decorations. The entrace area, the area in between the first two pitches and the area in the highest series are all loose and must be treated with care. A description and survey are available on my caving site as well as geological information. No control is placed over access, but you may want to check with the Brynmawr Caving Club to see if there are any restrictions.
