In reply to LP:
There is nothing around Aberaeron itself, although there is extensive bouldering further north at Borth. Do an online search, eg: http://skinnydogbouldering.blogspot.co.uk/2012/12/borth-bouldering-slice-of... There are some tidal issues re. access and there's a danger of being cut off by the tide. Similarly, there's stuff to do at Clarach, just north of the beach, but is not as good nor as extensive as Borth. Again, there are tidal issues here.
New Quay has some bouldering and easy climbing in the western bays below and beyond the fish factory (accessed via the old quarry on the headland above). Again. not as good nor as extensive as at Borth.
Further south there's highball stuff on Craig yr Enwau above the beach at Cwm Tydu. Again, the window of opportunity is limited as the crag's tidal.
A new guidebook - Central Wales - A climbing guide to Elenydd - should be in the shops within the next couple of months and has definitive coverage of all these areas as well as many, many others.
