In reply to FreshSlate:
Bus runs from Ashton to Greenfield, or used to so no problems there. Lots of crags within an hours walk then and Laddow is another 30 minutes.
Take it you are young and impecunious so forget trains most of the time, join a local group and get lifts and climbing partners.
I used to live in Denton, and would get the bus to Greenfield, or Glossop then walk up to Yellowslacks and over to Shining Clough or onto Kinder.
Don't own a guide book, you are not a climber yet. If you were, you would get the one for your area, and within three years own at least half a dozen.
They are the climbers drug, can't get enough of them.
