In reply to stuartholmes:
Does this not all depend on what type of wheelchair the user will have?
My wife has now been in a chair for a good few years and we do have an off road chair which makes getting places a little easier.
But if you start making claims like this crag is wheelchair accessible and this is then on a database somewhere, I am sure you are going to get a lot of angry comments from wheelchair user, that can not get in to certain areas.
One example given was the bowder stone. Now for me and my wife in the off road chair this would be an OK area to get to. An easy path with lots of bumps and stones to navigate, with one steep hill to make sure I was tiered before climbing. But for someone who is self-propelled with a non all terrain chair (even if it did cost £4k) would have little to no chance of getting in.
I think you need to think that little bit deeper about this.
I don't know if you yourself are in a chair but if you want to experience how hard it is to get someone into crag with even the easiest of walk-in's (and an off road chair) you are quite welcome to come and help me get my wife to say the Burbage South boulders. Ilkley - Cow and calf Millstone quarries.
It aint that easy
hope this gives you food for thought.
