In reply to Dan Glynn:
Get the climbers club guidebook to north Pembs. St David's is the best base. You have all the great short sandstone routes at places such as porth clais, caerfai and barcud, then some amazing longer routes on the micro granite at st David's head.
It's also got more to do for the non climber up there as opposed to south Pembs.
If you want any more info get in touch!
