In reply to Nuria Carballal:
This might not be the answer you're looking for, but I think the common (and good) answer is "climb a cool route on the sandstone tier". The terraces make it fairly easy to move from where you arrive to a choice of different routes on the quartzite tier.
Somebody else may be able to advise on the practicalities of getting direct onto the terrace, I'm not sure about that.
