This used to be a stable in Cork orienteering in the '80's, was open forest and ring forts. Then they cut the whole lot. Mapped by Southern Orienteers. It's not very convenient to Bantry though.
The ring forts are still there (according to the map at the entrance), but the open forest not so much. There are much nicer paces to run near Bantry! Just happened not to be near them last weekend.
