Get hold of the OS map OL41
High and Low Bentham are the extreme North boundary of this map and the map covers most of the Forest of Bowland.
Go west from Bentham and you will pass through Wray, Wennington, or Hornby and Lunesdale. The River Lune runs from Lancaster up past here to Kirkby Lonsdale and north.
I know this area well as I teach in the small village schools up Lunesdale, places like Arkholme, Wray, Melling etc. All of this area is fantastic for walking and watching wildlife. It just depends on what you want to do.
Morecambe Bay is superb for wading birds, the woods around Silverdale and Warton Crag are excellent and if you climb through them to the top you get fantastic views over Morecambe Bay. It depends on what your interests are. plenty of excellent country in the Forest of Bowland for tramping and getting lost. You could go down to Dunsop bridge and see if the eagle owls have arrived.
Go north and you have the dales, Ingleborough, Whernside and Pen y Ghent
I know your neck of the woods pretty well. We moved to Duffield when I was 11 and I went to school at Swanwick. My mother only left there two years ago when I brought here up here to Morecambe as she could no longer live on her own.
If you let me know any specific interests I might be able to be a bit more specific.
