This has been pinned in the wrong place! The arch where this is pinned is Bwa Ddu. The picture is labelled correctly but should be located north of Porth Swtan

Seeing these pink rocks came as a bit of a surprise, but they are a cool little feature that adds to the richness of the area and the cliff range.

Great little find!! Blink and you will miss it. So so cool. When walking there from the far side (as most would) it is to be found behind you once you go through the gate and across the little stream.
