Phil, Will find the route + map at home & post on here - Nancy's is more or less right, but it changed a couple of years ago, and I think the bit round Turton Res to the moors is now higher up the hill, as it was well and truly flooded one year !!
We'll be going on our own as we'll probably have a bit of helping out to do and also am calling round to see my niece - she's 1 on Sat !!
About 1 hour from Whaley, probably about the same from Macc but a 10 minute walk from car park to start.
The route that corresponds to Nancy's description is here, but as I say I think from CP3 to 686187 is now further up the hill.
