In reply to Jack Geldard - Editor - UKC:
"A quick search on the UKC Classifieds comes up with 39 walls within a 20 mile radius of central London." and a quick search of an A to Z will reveal that most of them might just as well be on a different planet by virtue of their location in relation to you in one of the world's bigger an dmore congetsed cities. The rest might as well also be on a different planet by virtue of their utter lack of quality or their restricted opening hours.
Cut to the chase - most Londoners have a wall that is about an hour away that is worth going to, but the nearest worthwhile crag needs a day trip (Harrisons doesn't count as a crag)
So where would you rather be? Well, Bristol would be a whole lot better for climbing, as would Sheffield, Gloucester, or Harrogate, or ....
I suppose that I am spolit, seeing as the new Craggy place is 10 minutes from home and I drive past the main Craggy on the way home from work, but I could get to the Bristol wall faster in the evening from work than I could to Mile End. Bristol I could do in about 2 hours. Mile End - maybe the same by train (or rather car, train, tube and walk). West Way - about 1 hr 15 by car (with luck - could be 2 hours). Probably 2 hours by train. The train tciket is about £20. Bargain.
