I am wondering if anyone has been to this cave recently. Are there any pictures of inside the cave? I found some references to it in a book called "GLENCREGGAN A HIGHLAND HOME IN CANTIRE BY CUTHBERT BEDE."
"But, whether or no we must date his arrival in Cantire to 503, or to 536, St. Kiaran, from the
very first, would seem to have made his abode in a cave on the sea coast, near to Kilkerran,
and about four miles and a half from Campbelton. It is where the eastern coast of Cantire
rounds off from Campbelton harbour towards the Mull. The spot is known as Achanhoan or
Achanatonn, signifying "The Field of the Waves," a name denoting the extensive sea view
visible from this place. Here, where the waters keep an everlasting murmur to the
precipices and crags that overhang them, is a wild and dreary cavern, hollowed from the
seaward rock. This was the home for the saint for many years; and it is called Cove-a-
Chiaran, "the Cave of Kiaran." It is difficult of access, and is only approachable at half tide,
and the road to it is covered with large stones, round and slippery. Other caves adjoin it.
Pennant thus describes them: — "Turn to the south, and visit some caves in the rocks that
face the frith. These are very magnificent, and very various ; the tops are lofty, and
resemble Gothic arches. One has on all sides a range of natural seats; another is in the
form of a cross with three fine Gothic porticoes for entrances. This had been the residence
of St. Kerran; had formerly a wall at the entrance, a second about the middle, and a third
far up, forming different apartments. On the floor is the capital of a cross, and a round
bason, cut out of the rock, full of fine water, the beverage of the saint in old times, and of
sailors in the present, who often land to dress their victuals beneath this shelter." The water
in the bason is supplied by the continual dropping from the roof of the cave. There is also a
rudely sculptured cross on a stone, upon which the saint is said to have sat and prayed."
