In reply to Tall Clare:
Here's an idea.
Eskdale and the Duddon Valley are two of the quietest and most beautiful valleys in the Lakes. You could park at Coniston (Walner Scar), and walk to the YH in Eskdale and back. Day one you could go via the Duddon Valley and maybe Harter Fell, the other day slightly more energetically over Crinkle Crags, crossing over Wrynose Pass, and onto the Coniston Fells back to the car.
Just thought of it now so couldn't give you distances or whatever, but it would definitely be two days of beautiful walking, one more valleys, one more hills. You could decide which way to go round depending on which is the better day on the tops.
