Torrent Falls Via Ferrata course is a great first rock-climbing experience. My son and I attended with his boy scout troop - about 50 kids/adults. They did a great job with such a large group. There are several areas of difficulty (area 2 is probably the easiest since area 1 starts out with a near straight up climb; area 6 is the most difficult). There are plenty of rebar hand/foot holds which allow you to litterly hang off the side of a sheer cliff. My son and I were both first time climbers (he's 11); it was a great test of anyone's climbing potential.
