In reply to Amy Eli:
Been a while since I done it but from what I can remember you have 3 sections... A, B & C, with each one getting slightly harder/more exposed. You can bail out at the end of each section. Access to the start of A is a straightforward path.
If i remember correctly, the hardest part physically of the whole route is a slightly overhanging ladder (about 10° over vertical) of about 12-15 rungs. Climbing the ladder is easy but you have to be sure they can hang on long enough to move their lanyards above the safety wire supports.
You could always carry a short scrambling rope and back them up if you were worried that they might fall or get into difficulties clipping their lanyards on the steeper sections.
Hope this helps, have a great time.
