In reply to Robert Durran:
We were there in July 2014 and had no problem with access to the normal route. IIRC part of the reserve is gated off and you need a local guide to get access, but this only applies to the back side of the peaks (away from the camping), and there aren't too many routes there. I think we had a decent web reference for this, I'll try and find it.
Regarding the normal route - UK HVS probably covers it. It's not too hard but it's definitely adventurous! Routefinding wasn't easy. I believe it can be made easier by traversing in above the first or second pitch, but I think this had some of the better climbing on it. Also, don't underestimate the approach - there's a lot of scrambling up/down/through boulders, and it was strenuous and time-consuming.
We did a few other things while we were there, and the other highlight was Watersports, a 3 pitch layback crack underneath an arch - photos here:

Oh, and it's a fantastic country - enjoy!
