The house and grounds are, at present, occupied by holidaying Hasidic Jews, which made any approach or conversation, let alone a look around the property, of Yr Ocar, impossible.
Sorry.
Outside the property there are many signs of diggings into the valley side but really little or nothing of any great import could be seen. If you didn't know it, seems unlikely that you'd guess it! Much of the area is deep in thick bracken which made walking around difficult and potentially dangerous as it hides many of the drops and falls on this steep slope. Very wet and slimy in places.
Classic signs of ochre however, slightly to the SE of Hirdir.
I take it that it is total coincidence that Bradites paint factory is only a stone's throw away!
