Camp on the moss, or there's a YHA in Dufton.
Day 2 - along to Knock and up the military road to Great Dun Fell, then carry on along the bridleway over the Tees to Tynedale.
Camp on the fells, or there's a YHA bunkhouse in Alston.
Day 3 - back over Yad Moss and down Teesdale back to Darlo. You could cut through Hamsterley if you wanted a bit more off-road, of course.
Might give that a go next week actually. Is that one you've done Dean?
