As above, Scugdale for easy soloing, Wainstones has reportedly decent bouldering. Goldsborough Carr is okay and not too far away. Some of the crags in the new North Yorks guide are good too.
That said, when I lived in County Durham, I nearly always opted for a long drive to Yorkshire grit: Slipstones, Brimham, Caley etc. For sport climbing... buy a van or look into caravans near Malham/ Kilnsey!
