In reply to Andrew Deacon: There really isnt much in the way of campsites along the Snake, or even really in Glossop, to my knowledge.
Pretty much the closest campsite is on the south side of Kinder in Edale, so its a hack up onto the top, and drop down onto the North side.
To get onto Bleaklow southern edge, maybe Crowden YHA is the "closest" place, but that really isn't close at all.
There are a couple of Shooting cabins on the south side of Bleaklow, but they aren't really good places to stay in unless youre just taking a bottle of whisky for an evening of quiet reflection.
In reply to Andrew Deacon: You used to be able to camp at Blagden Barn at the foot of Blagden Clough, but this was arranged for us as we were on D of E expedition training, and it was a long time ago. (might be spelled Blackden now!)
