In reply to nation1:
Very very very easy to traverse too early. At the common place to do so, there's even a short wall above you to entice you to do just that (and there may well be foot steps too!).
Basically, only traverse left when there is a big (and I mean biiiig) steep wall blocking the whole of the ridge immediately in-front of you.
Oh, and buy a guidebook... and a map... and a compass. Enjoy!!
