Park considerately, the road sees a fair bit of traffic and the farm building is also accessed fairly regularly. The walk in is on public footpaths as far as Im aware but Im not sure about the crag itself.
Routes are left to right as you come across them:

If you ask nicely and do a bit of light crag maintenance the crag moderator might send you a topo, though don't bank on it.
