Not sure what this type of rock formations is called, but they can found just south of Saligo Bay on the west coast of Islay. Saligo Bay in the distance in the centre of the picture, the Paps of Jura to the right in the distance.
There are some dramatic cliffs along the coast between Saligo and Sanaigmore, these three near Smaull probably the best known, as they are easily visible from Saligo Bay. Depending on who you ask the name might vary.
One of my favourite parts of Islay, the north west coast between Saligo and Sanaigmore, especially in the beautiful mild June evening light.
