In reply to ianghogg: Hi Ian,
I did a detailed map for the Bwlch y Moch section of Tremadog in my new guidebook which is the spot most people seem to find most confusing:

For the section you visited: My book also has a full page photo topo for Poor Man's.. area and a general crag over view photo for that too.
It sounds like you were in exactly the right place, but just missed the start of the route, it is tricky to identify.
You can find the base of the striking feature of Silly Arete - which is a few routes to the right and work from that.
PMP starts up a groove and if you check out the grooves in that area it isn't too difficult to figure out - once you know you're in the right general area. It also has PMP scratched in to it - not a practice I am recommending, but it might be of help to you in this instance.
It is virtually at the far left of the climbable rock and the groove heads up to a large tree.
Good luck - excellent route.
Jack
Thanks,
Jack
