Hope you had a good stay, although I suspect the A515 was a little noisy.
We live "just around the corner" in Over Haddon, and I can recommend Park House Campsite, Monsal Head, it's quiet and the guy does not overcrowd it. Two pubs within 5 minutes walk (The Stables at Monsal, and the Packhorse in Little Longstone.
Stayed there on Saturday night with my youngest daughter, and can really recommend it.
