Meaning "Cave of the dog", Ogof y Ci lies on the Nant-y-glais, a tributary stream of the Taf Fechan.

The cave is best approached by parking near to the Aberglais Inn on the Merthyr Tydfil to Pontsticill road. Walk downhill from the pub and take the public footpath alongside the road bridge over the Nant-y-glais. Follow the footpath north (upstream direction) climbing between trees. After a few hundred metres, the footpath drops and crosses a stile to meet the stream at a ford. (Ogof Rhyd Sych is in the gorge just below this point). Walk upstream on the western (left) bank for a few hundred metres until the valley starts to close in to form a craggy gorge and a resurgence is seen emerging on the western bank from boulders just above stream level. The entrance to the cave is above this resurgence.
