In reply to rattusrattus:
There's no sport up here* and top roping is discouraged at the popular crags owing to the soft rock being easily damaged. This doesn't seem to discourage people though, even where there are signs up at the crag. If I were you I'd go bouldering.
*The delights of Houghton Churchyard could be yours though.
edit: those "french grades" are bouldering grades.
