In reply to alex goodall:
Some great suggestions already, in south Pembrokseshire id add Newton Head upper tier (awesome dws underneath) it has a walk in.
Second saddle head, better to abb but not necessary.
In north Pembrokeshire, all the ones mentioned already plus:
Organ pipes (not amazing but walkable at low tide and lots of easy routes.
Pen y Cyfrwr is ok, one of the crags is non tidal which is a bonus, and there's a bit of dws there too.
Definitely check out st David's head south buttress. Walk in (high tide is ok but not in swell) lovely spot, and dws there too!
The scramble into caerfai isn't really recommended, super exposed and pretty loose in places, it'll only take another big storm to collapse the blocks. Awesome crag tho!
Get your mate abseiling and you'll obviously have a way better time!
Have a good one!
