Active Cave
Access Both entrances to the Cave lie at the rear of Rhongyr Isaf. At the rear of the garden, a stile on the left leads to a group of dolines, one of which contains an entrance. A second entrance which lies at the rear of the garden and is surrounded by a wooden fence is the safer and more pleasant way in.
Description An entrance series of awkward drops through thin beds to a stream which can be followed for a distance. This then leads via a 10 metre pitch to an impressive chamber enlarged on a junction of joints, with the stream entering as a waterfall higher in the roof. The passage continues for 750 metres until a sump is reached.
