Trough of Bowland, all areas of the Ribble and Hodder Valleys, you can hire boats on the Liverpool Leeds Canal and make a day of it, Manchester for night life and great Chinese restaurants, Southport for a nice day out shopping on Lord Street, Blackpool if you like the "kiss me quick hat" type of place (take plenty of money if you're going to the Pleasure Beach.) If you are prepared to travel further, as Grego says, the Lake District is a must, one of the most beautiful parts of the whole country.
