In reply to calvomatteo:
Wasdale is indeed nicer than Borrowdale, and Eskdale is nicer than both. However, they're also much farther away from almost anywhere, add at least an hour each way to your travelling time.
There's nothing wrong with Borrowdale, it gives easy access to all sorts of places including Scafell and Great Gable. But it seems to be traditional on UKC to say how horrible it is.
There's a very nice campsite at Grange, but it's quite a long way from the best scrambling. My favourite is the one on the bend on the main road just south of the Stonethwaite turn off. The Stonethwaite one is a bit closer to the hills but can be noisy.
There's also one at Seathwaite, which is handy for the Gable/Scafell area, but I haven't stayed there so can't comment.
