In reply to Webster:
> well no, by the British definition there are mountains in Dartmoor, Brecon beacons, peak district, Pennines etc etc... but none have the long multi pitch mountain routes you are after. Bosigran/commando ridge is probably the only route outside of the big 3 mountain areas which kinda meets your requirements, but from London its not much closer than N wales...
I have never, ever heard the hills of Dartmoor, B b, P D, or rest of Pennines described as mountains. What on earth is this alleged 'British definition' of mountains you are referring to?
