In reply to Allan McDonald (Gwydyr MC):
As above - check the "Find a crag" function on the logbook, but basically theres very little apart from the many sport routes around the quarries.
The map shows a small crag above Aber with 3xHVS, along with (rare) winter climbing on Aber falls, a grade ?2 scramble up Penmaen ridge and a few boulders.
Most of the Northern/Western Carneddau are open grassy 'whale-back' summits rather than pointy rocks, and even where there are glacial features they tend to be broken heather, and steep scree / boulder slopes rather than climbable cliffs.
In any case, Ogwen is only 15 minutes away - quicker to get to than the Ormes - and I believe there may be a climb or two there.
