In reply to katharinemcb:
Your best bet is granite climbing. Close to launceston Its quite easy to set up top ropes on the most popular walls at cheesewring quarry, and many of the other bodmin tors.
West penwith granite is much better quality. The best crag for top roping is definately trewavas head Trewavas. St loy and halldrine cove are decent. Also some routes at sennen or bosigran but a little more difficult access.
Or, just go to dartmoor which is closer. Sheeps tor.
If you're looking to avoid granite, zennor head has easy access etc and half a dozen good killas slate routes
