In reply to Jon Stewart:
> The Peak is annoying in July, Pembroke is so much better. I'm sure the OP can learn how to abseil, it doesn't take a genius to learn how to not die on a sea cliff.
The OP can perhaps learn to abseil, but what then? Fix a hanging belay and face the prospect of having to prusik out if they can't manage it? The OP made it plain he wanted to build confidence in placing gear and leading.
Maybe a day at Saddle Head and another at Bow Shaped Slab and Crystal Wall, for example, would be sufficient to give them that confidence, in which case they are set up to climb at the more challenging locations. However the OP was asking for a location with at least a week's worth of easy trad to and in my view a crag where they can walk in easily and have the option of lowering off or going round to place a top rope has to be a better option for building confidence than sea cliffs, which usually present a challenge just to access them. Of course it all depends on what you mean by 'easy' - to some it means V Diff, to others E1.
Once they have gained that confidence then I agree Pembroke is a must-visit
