In reply to Carolyn:
> Castlerigg Farm, se of Keswick, used to be a good compromise - out of town, but still within walking distance.
Second vote here for Castlerigg Farm: usually quiet, nice view to the W and you can walk straight out of the camp site and up on to the fells. I believe the pub at the bigger site site over the way is OK if you don't fancy the hike in to town.
That said, I've never stayed at Lanefoot so it's entirely possible that one might have its own advantages.
