In reply to fuzzysheep01:
I'm in this boat at the moment, being 17 and trying to do as much climbing as possible inside and out.
Most of the climbing I've done has been through my local club- Swaledale Outdoors Club - taking me cragging, which has been incredibly useful. I've now found an experienced partner my age.
I did first go to a climbing wall, which offered youth evening courses from 6-14 and 14-18, but I was put off by price (not unreasonable but still beyond me) and the longish drive there and back.
