Hi
I did the Six dales walk with Pure Challenge last year.
The walk is for the most part over steady ground through secluded dales, pretty villages and alongside streams with an abundance of wildlife.
There are some public toilets along the way and although it was well signposted by Pure Challenge with a decent map shouldn't find any problems to navigate yourself.
The ' walking englishman' website of this walk is almost identical to the route we did except we followed Weaddow Lane from Middleton to Dale End.
I clocked it exactly 28 miles and took me 9 hours excluding breaks.
Go ahead and do the walk, you won't be disappointed
