Kilcash Wood is a Coillte site in the village on the lower slopes of Slievenamon. I guess climbing Slievenamon takes the focus away from here as a walking destination. It is a fairly typical Coillte forest, evidently focused on commercial forestry.
However just inside the entrance I spotted a well, with an enclosure similar to a typical holy well, but nothing I could find in terms of inscriptions or the like around to indicate any specific practice here.
The well water was pretty muddy with a lot of plant material inside:
