Description
Length: 70m (ref 5)

Meaning "Cave of the stream", Ogof y Nant lies adjacent to the Sinc Ger y Ffordd site (which itself means "Sink near the road"). Water sinking here has been dye traced to Llygad Llwchwr some 6.4km away and 246m lower in altitude. It is possible that the water travels via the Ogof Gwynt yr Eira streamway some 400m away to the south (down-dip), but this has not been tested.

The cave is formed in some very shattered and loose rock so care is required.
