Do you mean you want to go off road or on the public highways? If you mean public roads then the Trough of Bowland is a great drive, lovely scenery, twisty roads and all that. Wouldn't recommend going tomorrow though, we're on the edge of the forest of bowland and quite a few of the minor roads are flooded, I should imagine it's the same (if not worse) in the trough.
Agree with spudqueen the trough is really lovely. I like it near Stonyhurst college as well not sure if that is classed as Bowland. The moors near Belmont are nice as well
