In reply to Scarab9:

Ken Wilson published a book called Classic Walks with Richard Gilbert, a long time ago. It has a selection ofwalks form around the country, contributed by a whole host of notable authors. It's been out of print for a long time, but copies may be available on eBay or AbeBooks.
However, it's not as good as Irvine Butterfield's High Mountains, which someone else has very sensibly recommended. Butterfield's book is terrific, and as inspiration for days out in Scotland, can't be bettered. The inclusion of selected hill in England and Wales was probably a bit of an afterthought, but is nice to see.
