Yes, very true, although the landings are often a bit, er, hostile and most is purposely undocumented. There's bouldering here:
Clegyrau Graig Isaf but it's not that remote. This might be better from a remoteness POV:
Mynydd Cwm-mynach The landings are friendly too. There's actually a much better area that's still being developed (so not yet on UKC - or indeed anywhere), a couple of miles away, which is equally remote .... but also with good landings.
This area is very good, but hardly remote:
Bala Boulders Not far away from Llanuwchlyn, to the west, is Rhobell Fawr. Its relatively remote and extremely rocky eastern and southern slopes might fit the bill. You could end up wandering around these hillsides with a mat for days on end.
But for both full-on remoteness and top quality, this area is comparable to the very best in Snowdonia
Pumlumon Boulders The rock is a sublime gritstone. The only drawback is that it isn't in, er, North Wales. Go there; you won't see a soul and it's a place where the slopers, slaps and crimps are refreshingly chalk free. There's even a topo guide.
