I can't help directly as I don't know the area.
However, have a look at Bing Maps. One of the options on Bing is OS maps(which are always my first port of call in a new area) which gives all the usual detail. I've just had a look and within a few miles of Grange over Sands is a viewpoint at Hampsfell, Cartmel Priory and Holker Hall.
If there is any area on the OS map that looks interesting have a look on Geograph. There is a good chance someone will have photographed it and posted on the Geograph site.
