So, to make it easier, and because I wanted to check out a Peak District campsite, today I've travelled as far as Leek (which is about half way to Cumbria) where I'm spending the night at the Camping & Caravan Club's site.
The campsite is tidy and peacefull. It's a bit muddy in places but the price is right; I'm in my campervan for the night so it's £7.95 for a hard surfaced pitch, with hook-up to a 16 Amp electric supply, and there's access to a clean ablutions block with hot showers etc. There's no pub handy but I'm carrying everything that I need - including the kitchen sink and hob.
Keswick from tomorrow till Thursday, and then south-east to Hartsop where I'll be based until Monday. Someone else to do the cooking from tomorrow (and pull pints). Luxury!
