Description
A peculiar cave which may be natural, but has been modified by digging. There is a main chamber with a smaller alcove and a passage
leading up a slope to a dead end. There seems to be signs of digging in the main chamber to the S. I originally thought this was Ogof
Hen Ddyn until Cris Ebbs put me right. Neither he or Selwyn Edwards had known about his before.
Unexplored Passages
None
Digs
There are a few old ancient digs
